Resolved a client hang in the scenario where the client sent loadendack before the server finished loading all data (bugreport:3700).

Improved the performance of pc_autosave() to stop scanning players after it has already found the player it wanted to save (bugreport:3717).
The 'overweight' status changes (SC_WEIGHT50/SC_WEIGHT90) will now be cleared on logout, to avoid saving them into the database (they get derived from player weight during login anyway).
Improved lock.c on windows to use C's access(0) function instead of doing fopen/fclose when testing for existence of files.
Re-added the 'static' attribute to mapindex_getmapname_ext's buffer; returning the address of a non-static local variable is undefined behavior (see r13901).
