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.

ea1a4b7932 Explicitly annotate intentional switch fallthrough 
This silences a very useful warning in GCC 10.

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

8087f603ad Stub out __has_attribute if not defined 
Otherwise compilers that don't even have __has_attribute fail.

Fixes #7554

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.

1365379518 Optimize away a str2wcs_internal check 
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
time.

84e0c8d32e Guard thread_local 
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
define guard.

Fixes #7023

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.

__packed.

b6555a0dc4 Add print-rusage-self to fish 
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
way. This will be used by upcoming benchmarking support.

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.

d1913f0df0 Add workaround for Cygwin process management and job control bugs 
We cannot wait by pgroup under Cygwin for unknown reasons. Always
wait on jobs by individual processes. See code for more information.

9f8ae95b0e Initial CMake import 
This adds a basic CMakeLists.txt. It also adds a ConfigureChecks.cmake
and config_cmake.h.in that produces a config.h.
