[lldb] [Process/NetBSD] Copy the recent improvements from FreeBSD

Copy the recent improvements from the FreeBSDRemote plugin, notably:

- moving event reporting setup into SetupTrace() helper

- adding more debug info into SIGTRAP handling

- handling user-generated (and unknown) SIGTRAP events

- adding missing error handling to the generic signal handler

- fixing attaching to processes

- switching watchpoint helpers to use llvm::Error

- minor style and formatting changes

This fixes a number of tests, mostly related to fixed attaching.

[lldb] Split out NetBSD/x86 watchpoint impl for unification

Split the current NetBSD watchpoint implementation for x86 into Utility,
and revamp it to improve readability. This code is meant to be used
as a common class for all x86 watchpoint implementation, particularly
these on FreeBSD and Linux.

The code uses global watchpoint enable bits, as required by the NetBSD
kernel. If it ever becomes necessary for any platform to use local
enable bits instead, this can be trivially abstracted out.

The code also postpones clearing DR6 until a new different watchpoint
is being set in place of the old one. This is necessary since LLDB
repeatedly reenables watchpoints on all threads, by clearing
and restoring them. When DR6 is cleared as a part of that, then pending
events on other threads can no longer be associated with watchpoints
correctly.

[lldb] [Process/NetBSD] Fix handling concurrent watchpoint events

Fix handling concurrent watchpoint events so that they are reported
correctly in LLDB.

If multiple watchpoints are hit concurrently

[lldb] [Process/NetBSD] Fix handling concurrent watchpoint events

Fix handling concurrent watchpoint events so that they are reported
correctly in LLDB.

If multiple watchpoints are hit concurrently, the NetBSD kernel reports
them as series of SIGTRAPs with a thread specified, and the debugger
investigates DR6 in order to establish which watchpoint was hit. This
is normally fine.

However, LLDB disables and reenables the watchpoint on all threads after
each hit, which results in the hit status from DR6 being wiped.
As a result, it can't establish which watchpoint was hit in successive
SIGTRAP processing.

In order to workaround this problem, clear DR6 only if the breakpoint
is overwritten with a new one. More specifically, move cleaning DR6
from ClearHardwareWatchpoint() to SetHardwareWatchpointWithIndex(),
and do that only if the newly requested watchpoint is different
from the one being set previously. This ensures that the disable-enable
logic of LLDB does not clear watchpoint hit status for the remaining
threads.

This also involves refactoring of watchpoint logic. With the old logic,
clearing watchpoint involved wiping dr6 & dr7, and setting it setting
dr{0..3} & dr7. With the new logic, only enable bit is cleared
from dr7, and the remaining bits are cleared/overwritten while setting
new watchpoint.

[lldb] [Process/NetBSD] Copy watchpoints to newly-created threads

NetBSD ptrace interface does not populate watchpoints to newly-created
threads. Solve this via copying the watchpoints from the current thread
when new thread is reported via TRAP_LWP.

Add a test that verifies that when the user does not have permissions
to set watchpoints on NetBSD, the 'watchpoint set' errors out gracefully
and thread monitoring does not crash on being unable to copy watchpoints
to new threads.

[lldb] [Process/NetBSD] Remove unnecessary register buffer abstraction

Remove most of the abstraction over ptrace() register operations,
as it has little value and introduces more code than it saves.
Instead, leave a single ptrace() wrapper method and call it directly
from ReadRegisterSet() and WriteRegisterSet() with correct PT_* request
and buffer.

Remove the remaining direct ReadGPR() and WriteGPR() invocations
with ReadRegisterSet() and WriteRegisterSet().

Cleanup suggested by Pavel Labath in D63545.

Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Clean up NativeRegisterContext

Summary:
This commit removes the concrete_frame_idx member from
NativeRegisterContext and related functions, which was always set to
zero and never used.

I also change the native thread class to store a NativeRegisterContext
as a unique_ptr (documenting the ownership) and make sure it is always
initialized (most of the code was already blindly dereferencing the
register context pointer, assuming it would always be present -- this
makes its treatment consistent).

Rename Error -> Status.

This renames the LLDB error class to Status, as discussed
on the lldb-dev mailing list.

A change of this magnitude cannot easily be done without
find and replace, but that has potential to catch unwanted
occurrences of common strings such as "Error". Every effort
was made to find all the obvious things such as the word "Error"
appearing in a string, etc, but it's possible there are still
some lingering occurences left around. Hopefully nothing too
serious.

Introduce FPR and Debug Registers/NetBSD/amd64 support

Summary:
This code offers Debug Registers (80386) model in LLDB/amd64.

This is initial support and has one issue that will be addressed later,
Debug Register trap (TRAP_DBREG) is registered as (TRAP_TRACE)
for unknown reason. On the other hand this works good enough to
move on and leave this bug to be squashed later.

Improve the NativeProcessNetBSD::ReinitializeThreads() function,
stop setting inside it SetStoppedByExec(). This fixes incorrect
stop reason on attaching (SetStoppedBySignal(SIGSTOP)).

This commits also has no functional style improvements from
clang-format.

This code also ships with FXSAVE support on NetBSD.

Battery of NetBSD support improvements

Summary:
Include initial support for:
- single step mode (PT_STEP)
- single step trap handling (TRAP_TRACE)
- exec() trap (TRAP_EXEC)
- add placeholder interfaces for FPR
- initial code for NetBSD core(5) files
- minor tweaks

While there improve style of altered elf-core/ files.

This code raises the number of passing tests on NetBSD to around 50% (600+/1200+).

The introduced code is subject to improve afterwards for additional features and bug fixes.

Add support for tracing hello-world application on NetBSD

Summary:
This patch is a stripped down from features a NetBSD process
code (patch is kept under 2k LOC). This code has assumption that
there is only one thread within a debugged process. The only
debugger trap supported is software breakpoint (TRAP_BRKPT).
The generic platform code requires to add dummy function for
watchpoints etc. These functions are currently empty.
This code is not the final platform support as is and it's treated as
a base to extend, refactor and address issues afterwards.

Supported features:
- handle software breakpoints,
- correctly attach to a tracee,
- support NetBSD specific ptrace(2),
- monitor process termination,
- monitor SIGTRAP events,
- monitor SIGSTOP events,
- monitor other signals events,
- resume the whole process,
- get memory region info perms,
- read memory from tracee,
- write memory to tracee,
- read ELF AUXV,
- x86_64 GPR read and write code

For the generic framework include:
- halt,
- detach,
- signal,
- kill,
- allocatememory,
- deallocatememory,
- update threads,
- getarchitecture,
- getfileloadaddress,
- and others.

This code has preliminary AddThread code.

Out of interest in this patch:
- exec() traps,
- hardware debug register traps,
- single step trap,
- thread creation/termination trap,
- process fork(2), vfork(2) and vfork(2) done traps,
- syscall entry and exit trap,
- threads,
- FPR registers,
- retrieving tracee's thread name,
- non x86_64 support.

This code can be used to start a hello world application and trace it.

This code can be used by other BSD systems as a starting point to get similar
capabilities.

Break the cycle between Host and PluginProcessUtility.

There are only two users of NativeRegisterContextRegisterInfo,
and both are in process plugins. Moving this code from Host
to Plugins/Process/Utility thus makes sense, and as it is the
only dependency from Host -> PluginProcessUtility, it also
breaks this cycle, reducing LLDB's overall cycle count from
45 to 44.

Add stub for PluginProcessNetBSD

Summary:
This is the base for introduction of further features to support Process Tracing on NetBSD, in local and remote setup.

This code is also a starting point to synchronize the development with other BSDs. Currently NetBSD is ahead and other systems can catch up.
