FILE_SUPPORTS_REPARSE_POINTS, FILE_SUPPORTS_REMOTE_STORAGE,

* lib/psapi.def: New file.
* spawn.cc (_spawnve): Ditto.
* passwd.cc: Remove static from `passwd_in_memory_p'.
(read_etc_passwd): Remove static.
* uinfo.cc: Move global declaration of `read_etc_group' and
`group_in_memory_p' into `uinfo_init'.
(internal_getlogin): Try to get SID from current process first.
(uinfo_init): Don't set uid and gid if `myself' has a valid SID.
Only load /etc/passwd and /etc/group in that case.
for existing user hive.
Use MAX_PATH instead of numerical constant for array size.
Use return code of RegLoadKeyA instead of GetLastError for error output.
* libc/include/sys/reent.h (_rand_next): Added __extension__
qualifier as long long type is not strict ANSI.

`internal_getlogin' from child process in case of changing user context.
Call `load_registry_hive' in case of changing user context.
(_spawnve): Copy user infos only if user context remains the same.
* uinfo.cc: Add load statement for `NetUserGetInfo'.
Remove load statement for `NetGetDCName'.
(internal_getlogin): Rewrite to speed up process startup
