Log:
[SECUR32][NTOS]: Update the LSA export signatures for the functions that are implemented
in the "lsalib" library.

[LSALIB]
- Add old-school annotations (as we currently do in our main .c code of our stuff).
- Mention that LsaConnectUntrusted is not an API that is exported (& implemented) by
ntoskrnl.
- For LsaRegisterLogonProcess, we first wait for the LSA server to be ready (by waiting on
its initialization event). This is TODO for LsaConnectUntrusted on the contrary.

[LSALIB][NTOS]
Usa the lsalib as the implementation of the LSA functions exported by ntoskrnl. But for
that we need to recompile the lsalib as a library that can be used from inside ntoskrnl,
because it needs some functions that are normally exported by ntos. For this purpose I add
the library target "ntlsalib" (which also specify different #defines), to
differentiate it from the (user-mode) "lsalib" one that is used by secur32.dll
(Amine, if you have a better idea on how to do that, please let me know!).
