[lldb] Check for and use ptsname_r if available

ptsname is not thread-safe. ptsname_r is available on most (but not all)
systems -- use it preferentially.

In the patch I also improve the thread-safety of the ptsname fallback
path by wrapping it in a mutex. This should guarantee the safety of a
typical ptsname implementation using a single static buffer, as long as
all callers go through this function.

I also remove the error arguments, as the only way this function can
fail is if the "primary" fd is not valid. This is a programmer error as
this requirement is documented, and all callers ensure that is the case.

you forget to include Config.h.

Detect HAVE_SYS_TYPES_H in lldb

Summary:
After rL368069 I noticed that HAVE_SYS_TYPES_H is not defined in
Platform.h, or anywhere else in lldb. This change fixes that.

[cmake] Move LLDB_DISABLE_LIBEDIT handling code into a central place

This was previously scattered between the main CMakeLists.txt file and
LLDBGenerateConfig.cmake and LLDBConfig.cmake. This caused the some of
the code to be executed in incorrect order. Specifically, the check for
el_winsertstr was done before libedit_LIBRARIES was computed, and so it
always failed on the first run.

Moving it the two checks to a central place makes sure this doesn't
happen again and improves the overall readability.

[cmake] Detect presence of wide-char libedit at build time

Summary:
Instead of hardcoding a list of platforms where libedit is known to have
wide char support we detect this in cmake. The main motivation for this
is attempting to improve compatibility with different versions of
libedit, as the interface of non-wide-char functions varies slightly
between versions.
