[jmorlan] 34227: - Don't use ntdll's RtlDuplicateUnicodeString in kmode; it allocates from the process heap. Instead, allocate from pool and copy the string manually. - Get rid of other ntdll imports (memcmp in freetype, tan in win32k) and instead link the functions statically, so ntdll is no longer loaded at all in kmode. Saves about 550kB of memory. - Also remove unused <library>hal</library> in freetype.

Log:
- Don't use ntdll's RtlDuplicateUnicodeString in kmode; it allocates from the
process heap. Instead, allocate from pool and copy the string manually.
- Get rid of other ntdll imports (memcmp in freetype, tan in win32k) and instead link the
functions statically, so ntdll is no longer loaded at all in kmode. Saves about 550kB of
memory.
- Also remove unused <library>hal</library> in freetype.
