Moves low-level functions handling to os/fs.c. Adds file.c with a proxy
interface.
Target: while leaving syscalls handling is os.c (partially handled by libuv),
add buffering for reading and writing to file.c.
The TUI can be enabled/disabled at build time with -DFEAT_TUI, default is ON for
UNIX, and OFF for non UNIX. When off, Neovim prints a message to stderr, along
with a list of the server endpoints.
This was noticed due to a user issue (#4750) when building Neovim 0.1.4
via ports. The crux of the issue is that we did not detect the
be64toh() macro, because there is no endian.h on FreeBSD (along with
several other BSDs). So we were defaulting to our builtin version of
be64toh(). However, it appears that sys/endian.h was being picked up by
an include (likely msgpack.h) and so be64toh() was actually defined and
corrupting our definition of it.
So the answer here was to use the correct include file in our check, and
export that information in the config.h. Then we use that information
to include the right header in shada.c.
This fixes#4750.
Change POROJECT_NAME to 'nvim', and use it as the gettext
domain name. The *.mo files, previously installed as
$runtime/lang/xx/LC_MESSAGES/nvim.mo, are now installed as
$prefix/locale/xx/LC_MESSAGES/nvim.mo.
Unix systems must have this header but Windows does not have it at all.
Since src/nvim/os/unix_defs.h includes <unistd.h> without the guard
in order to avoid including this in the numerous places we would
need <unistd.h> on Unix we just include src/nvim/os/os.h which will pull
in <unistd.h> for us.
In Vim, at least the constant `I_PUSH` is used from <stropts.h>, but
Neovim doesn't seem to use anything from said header.
Besides that, POSIX.1-2008[1] marks this header as obsolescent, and
there don't seem to be many platforms that even have it.

Windows does not have setenv(), instead the _putenv_s() function is used - added
a function check and fatal errors. Implemented os_setenv() for Windows.
Vim supports the original putenv() function if no alternative is available.
Neovim only supports systems where safer alternatives exist, so the check for
putenv() was removed from config/CMakeLists.txt.
If nvim is built from a non-tagged commit, the truncated commit hash is
already appended to the main version string (e.g., "NVIM v0.1.0-83-g959f260 ..."),
making the "Commit:" field redundant.
Regarding the truncated hash length: we don't have nearly enough commits
to worry about collisions, and probably won't ever, so the default
length should be fine.
When building in a git repo:
- If HEAD corresponds to an annotated tag, (i.e. git_get_exact_tag()
returns truthy) the current build is considered a "release" build:
NVIM_VERSION_MEDIUM is directly assigned the tagged version name,
and NVIM_VERSION_* defines are ignored.
- If HEAD is not a tagged release, then NVIM_VERSION_MEDIUM is
directly assigned the result of `git describe`.
If git (or the repo) is not available:
- The NVIM_VERSION_* defines are used to define NVIM_VERSION_MEDIUM.
Sample outputs for `nvim --version` and `nvim +version`:

* Hide commit information from --version if we can't find any (e.g. when
building from tarball).
To define a release in CMake, set NVIM_VERSION_PRERELEASE to "".
This will modify --version output to:
* Show annotated Git tag instead of commit hash (NVIM_VERSION_COMMIT).
* Hide commit date (NVIM_VERSION_BUILD).
RETSIGTYPE, SIGRETURN, and SIGDEFARG are always defined the same, so
inline them for simplicity; SIGDUMMYARG, however, is unused, so remove
it.
Even if these things don't work on windows, the signal handler in
if_cscope.c is already wrapped with '#idef UNIX', as is its only call
site.

Removed unneeded platform checks from config/config.h.in and
config/CMakeLists.txt
- HAVE_OSPEED and HAVE_UP_BC_PC were used by the old UI, and are
no longer needed.
- sigvec() was used as part of the signal handling code in os_unix.c, but it is
no longer used in Neovim.
- The function lstat() is no longer used, replaced with libuv.
* Set JEMALLOC_NO_DEMANGLE to be able to use `je_*` functions,
regardless of how jemalloc was compiled (--with-jemalloc-prefix)
* Show jemalloc information in Neovim's version output.
Resolve#2449.
- In UNIX systems where unsetenv() is available, it is used. Otherwise
the variables are set with the empty string.
- New check HAVE_UNSETENV for unsetenv()
- Added unit test to env_spec.lua
Jemalloc will be used if the cmake option `USE_JEMALLOC` is enabled(which is the
default). To avoid trouble with clang's ASAN, it is disabled by default if the
`SANITIZE` option is enabled.
Since jemalloc has thread cache for small objects, it fills the gap created by
removing klib memory pools.
The `xstrdup` funciton(memory.c) had to be reimplemented on top of `xmalloc` to
make it work with a custom allocator.
- Remove abstract_ui global, now it is always active
- Remove some terminal handling code
- Remove unused functions
- Remove HAVE_TGETENT/TERMINFO/TERMIOS/IOCTL #ifdefs
- Remove tgetent/terminfo from version.c
- Remove curses/terminfo dependencies
- Only start/stop termcap when starting/exiting the program
- msg_use_printf will return true if there are no attached UIs(
messages will be written to stdout)
- Remove `ex_winpos`(implement `:winpos` with `ex_ni`)
Problem : Argument cannot be negative @ 1165.
Diagnostic : Real issue.
Rationale : len can be assigned a negative value @ 1162;
len is passed as an unsigned argument @ 1165.
Resolution : Refactor variable's types:
- Use ftello instead of ftell to avoid using long.
- Assert ftello result is safely convertible to size_t.
- Introduce variable read_size to avoid using i (int).
Problem : Operands don't affect results (CONSTANT_EXPRESSION_RESULT).
Diagnostic : Harmless issue.
Rationale : n >= LONG_MIN, n being intmax_t, is always true for
architectures where sizeof(intmax_t) == sizeof(long).
Resolution : Add sizes check.
put_time() had a complicated implementation, because of having to shift
an 8-byte value in a portable way with old means.
That can be greatly simplified now, using a C99 fixed-size type.
Can't reliably get this information from cmake (#1267), so it's
misleading to show these messages at all. We can always revert this
commit if we find a way later.
- cmake: git_timestamp() returns last commit time formatted as
`YYYYMMddHHmm`.
- Always include commit hash in :version and --version output.
`nvim --version` sample output:
