llvm-mingw's static runtime (libc++, libmingwex, libc++abi, libunwind)
references symbols the NT 5.2 export surface does not provide. Add a
static library, linked into the Clang runtime chain below
DLL_EXPORT_VERSION 0x601, providing:
- C99 vsnprintf/snprintf on top of _vsnprintf/_vscprintf.
- __imp_* aliases binding dllimport references to the static CRT
definitions instead of ucrtbase import thunks, which collide with
them (lld: "<sym> was replaced").
- K32EnumProcessModules, forwarded to psapi's EnumProcessModules.
- The Win7 SRW lock and Vista condition variable surface, bound to the
RTL implementation linked statically from rtl_vista. Modules get one
self-contained, consistent synchronization implementation (ReactOS'
lock layout is not Windows-compatible), no kernel32_vista.dll
dependency, and stay runnable on any Windows version. Static SRW
linking suggested by Timo Kreuzer.
Address review feedback on the llvm-compat shims:
sync_static.c now uses the proper SDK/NDK headers with WINAPI/NTAPI, imp_alias.h
moved to sdk/include/reactos and fixes the msvcrtex slot decorations too, and a
new InitOnceExecuteOnce shim lets us drop libkernel32_vista from the interface.
