wchar_t has better cross-platform support and seems to fix an issue
on MinGW when building with `-std=c99`.

Since exe_name is a stack allocated array, we need it to be in scope for
the lifetime that vim_path points to it.

Do this on all systems, so that portable builds work everywhere. This
allows us to ship archives with this folder structure:
bin/nvim
share/nvim/runtime
then ./bin/nvim works without the user needing to explicitly set VIMRUNTIME.

This allows executables to be found by :!, system(), and executable() if
they live next to ("sibling" to) nvim.exe. This is what gvim on Windows
does, and also matches the behavior of Win32 SearchPath().

Closes #731
References #851
Note: This does not remove some intentional legacy usages of strncpy.
- memcpy isn't equivalent because it doesn't check the string
length of `src`, and doesn't zero-out the remainder of `dst`.
- xstrlcpy isn't equivalent because it doesn't zero-out the
remainder of `dst`. Some Vim logic depends on that (e.g.
ex_append which calls vim_strnsave).

In Windows we cannot rely on absolute install paths to point to the
location of the runtime. Vim uses the path of the current binary as
a possible location for the runtime folder. In Neovim the install
location places the runtime folder in ../share/nvim/runtime.
In Vim this logic is guarded by USE_EXE_NAME, which is defined for win32
and macOS.
TODO: We may need to incorporate similar logic for macOS:

...and small refactorings:
- Style changes
- Variable renames
- Changes in variable scope
This change won't bring new problems (undefined behavior) as `memcpy` is
already being used in the function.

Change POROJECT_NAME to 'nvim', and use it as the gettext

$runtime/lang/xx/LC_MESSAGES/nvim.mo, are now installed as
$prefix/locale/xx/LC_MESSAGES/nvim.mo.

Although UNIX is a registered trademark of The Open Group, it doesn't
really matter whether we refer to these systems as UNIX, Unix, or
Unix-like. So, for consistency, refer to them collectively as Unix.

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.

variables as having been unset. For all others, use os_env_exists().

Without the casts*, the compiler rightly warns about the os_getenv
