Some fixes for console alias functions:

Some fixes for console alias functions:
- Pass buffers via a CSR capture buffer, instead of trying to cram them in the size-limited LPC message.
- GetConsoleAliasW: Return number of bytes written, not unrelated "Size" variable.
- GetConsoleAliasExesW: Return value is in bytes, not characters.
- GetConsoleAliasA, GetConsoleAliasExesA: Parameters and returns of corresponding W functions are in bytes, not characters.
- IntFindAliasHeader, IntGetAliasEntry: Break when current name is greater, not less.
- IntCreateAliasHeader: Fix bad use of pointer arithmetic; initialize Data to NULL.
- IntCreateAliasEntry: Fix bad use of pointer arithmetic.
- IntGetConsoleAliasesExesLength: Fix infinite loop; add sizeof(WCHAR) instead of 1.
- IntGetAllConsoleAliasesLength: Fix infinite loop.
- CsrGetConsoleAlias, CsrGetAllConsoleAliases, CsrGetConsoleAliasesExes: Don't use a winerror where an NTSTATUS is needed.
