Always use LC_NUMERIC=C internally (#8204)
In most cases, like math, we want C-semantics for floating point
numbers. In particular "." needs to be the decimal separator.

Instead, we pay the price in printf, which is currently the sole place
to output in locale-specific numbers and attempt to read them and
C-style ones.

f9def20180 Update ConfigureChecks, only do the mtime hack for Linux.. on Linux
- Only check for HAVE_CLOCK_GETTIME and HAVE_FUTIMENS on Linux, since
they are only used to implement a Linux-specific workaround related
to mtime precision.
- Make sure that hack is limited to Linux builds
- HAVE_SYS_SYSCTL_H was unused, but we should have been using it
- HAVE_TERMIOS_H was unused, remove it

The only functional change is that unix machines with clock_gettime
and futimens will not bother with a Linux-specific hack, and won't
waste time checking for either during cmake configuration either.

Replace strerror/sys_errlist after fork with our own errors (#8234)
* Remove safe_strerror, safe_perror and safe_append

This no longer works on new glibcs because they removed sys_errlist.

So just hardcode the relevant errno messages (and phrase them better).

Fixes #4183.

8066428feb Add fd_event_signaller_t
fd_event_signaller_t exists to expose eventfd under Linux. This is a
more lightweight way of signalling events than using a pipe.

b79ec0122a Use pipe2 when creating pipes if avaialble
This allows us to avoid marking the pipe as CLOEXEC in some cases,

364c6001dc Introduce __warn_unused_type
This is like __warn_unused, but it says that any time this type is
returned from a function it must be used. This will help enforce error
handling.

str2wcs_internal is one of worst hot paths in the codebase, and this
particular check can be optimized away for non-macOS hosts at compile

Mac OS X 10.9 supports __thread but not C++11 thread_local.
Teach CMake to detect support for thread_local and use the proper

934f708ef6 cmake: adjust logic for TPARM_VARARGS
- Define it before the headers so they can pick the variadic tparm
prototype.
- We need a TPARM_VARARGS define, add it to config_cmake.h.
- Move & adjust comment - put it near the code, and mentiont that
NetBSD curses doesn't need the kludge.

Now variadic tparm is used on NetBSD instead of the Solaris kludge.

87854c81f5 Allow C++ standard to be passed to CHECK_CXX_SOURCE_COMPILES
Work around the issue in CMake where C++ standard doesn't get propagated
to CHECK_CXX_SOURCE_COMPILES. Also correctly check for std::make_unique;
the define was missing from the config.h header.

This adds an option --print-rusage-self to the fish executable. When set,
this option prints some getrusage stats to the console in a human-readable

2bb53f7253 Fix locale_t under macOS 10.10
`xlocale.h` is not available on Linux, so we can't just universally
include it.

`HAVE_XLOCALE_H` was already being tested/set in the CMake script as a
possible requirement for `wcstod_l` support, this just adds it to
`config_cmake_h.in` and uses it in `wutil.h` to gate the include.
