[libc] apply new lint rules

This patch applies the lint rules described in the previous patch. There
was also a significant amount of effort put into manually fixing things,
since all of the templated functions, or structs defined in /spec, were
not updated and had to be handled manually.

This introduces gmtime to LLVM libc, based on C99/C2X/Single Unix Spec.

This change doesn't handle TIMEZONE, tm_isdst and leap seconds.

Moved shared code between mktime and gmtime into time_utils.c

[libc] [Obvious] Fix.


# 034f5629 23-Feb-2021 Raman Tenneti <[email protected]>

Changes to mktime to handle invalid dates, overflow and underflow andcalculating the correct date and thenumber of seconds even if invalid datesare passed as arguments.

Added tests for invalid dates like the following
Date 1970-01-01 00:00:-1 is treated as 1969-12-31 23:59:59 and seconds
are returned for the modified date.

Tested the code by doing ninja check-libc (and cmake).

[libc] Switch to use a macro which does not insert a section for every libc function.

Summary:
The new macro also inserts the C alias for the C++ implementations
without needing an objcopy based post processing step. The CMake
rules have been updated to reflect this. More CMake cleanup can be
taken up in future rounds and appropriate TODOs have been added for them.

Initial commit of mktime.

This introduces mktime to LLVM libc, based on C99/C2X/Single Unix Spec.

Co-authored-by: Jeff Bailey <[email protected]>

This change doesn't handle TIMEZONE, tm_isdst and leap seconds. It returns -1 for invalid dates. I have verified the return results for all the possible dates with glibc's mktime.

TODO:
+ Handle leap seconds.
+ Handle out of range time and date values that don't overflow or underflow.
+ Implement the following suggestion Siva - As we start accumulating the seconds, we should be able to check if the next amount of seconds to be added can lead to an overflow. If it does, return the overflow value. If not keep accumulating. The benefit is that, we don't have to validate every input, and also do not need the special cases for sizeof(time_t) == 4.
+ Handle timezone and update of tm_isdst
