the standard[1].

a8fefd89cd Everywhere: Make some symbols __attribute__((used)) for LTO 
With these changes, the userland builds correctly with Clang's ThinLTO
enabled.

95c32fdf19 LibC: Primitively implement wcsxfrm 
The `wcsxfrm` function copies a wide character string into a buffer,
such that comparing the new string against any similarly pre-processed
string with `wcscmp` produces the same result as if the original strings
were compared with `wcscoll`.

Our current `wcscoll` implementation is simply an alias for `wcscmp`, so
`wcsxfrm` needs to perform no actions other than copying the string.

e6164d35fa LibC: Fix wcsrchr declaration to return a non-const wchar* 
This is how the standard specifies it; similarly to the already
correctly declared wcschr function.

685045176b LibC: Add ELAST errno macro 
The ELAST macro is used on many systems to refer to the largest possible
valid errno value. LLVM's libc++ uses errno values of ELAST+1 and
ELAST+2 internally, and defines an arbitrary fallback value for
platforms which don't have the macro. This means that it's possible for
their internal errno numbers could coincide with values we actually use,
which would be a very bad thing.

b5fcb10493 LibC: Forward-declare struct tm in wchar.h 
The C standard specifies that this forward-declaration be present in
wchar.h, and is needed in order to build libstdc++.

c8367df746 LibC: Implement wcrtomb 
This function converts a single wide character into its multibyte
representation (UTF-8 in our case). It is called from libc++'s
`std::basic_ostream<wchar_t>::flush`, which gets called at program exit
from a global destructor in order to flush `std::wcout`.

20fc93410c LibC: Mark termcap symbols as weak 
Otherwise, we may end up preferring those over the more accurate
implementation in ncurses (if available).

8ac1e6e73b LibC: Use the new pread syscall to implement pread 
This new implementation of pread saves two lseek system calls and is
thread-safe thanks to it simply forwarding the call to the pread system
call.

f9a4f4f7e6 LibC: Fix redeclaration in x86_64/regs.h 
In QtCreator (and under weird configurations with gcc), this used to
fail with the error messages like: "error: member of anonymous union
redeclares '___'".

This patch gives each member a unique name.

06f30943ef LibC: Manually count stored bytes in mbstate_t 
This is probably a bit faster than constantly having to look through all
stored bytes. It also helps when we are trying to store actual null
bytes.

3c807402b3 LibC: Remove the mbstate_reset helper 
A zero-initialized mbstate_t struct has to be a valid initial state, so
we can just zero-initialize it whenever we need to reset.

Having a helper function for resetting the struct might imply that you
can add additional setup operations afterwards, which is not the case.

a67e06184b LibC+LibELF: Add definitions for extra dtags 
These are found in some libraries, and LibELF doesn't know how to handle
them, not even their name. Adding these definitions should at least help
readelf display information correctly, but more work is needed to
actually implement them.

It is marked as LEGACY but still used in projects such as PHP.
