Add file open flags FILE_FLAG_OPEN_REPARSE_POINT and

FSCTL_SET_REPARSE_POINT and FSCTL_DELETE_REPARSE_POINT.
* winnt.h: Add typedef for GUID.
Add file attributes FILE_ATTRIBUTE_ENCRYPTED,
FILE_ATTRIBUTE_SPARSE_FILE, FILE_ATTRIBUTE_REPARSE_POINT and
FILE_ATTRIBUTE_NOT_CONTENT_INDEXED.
Add volume attributes FILE_VOLUME_QUOTAS, FILE_SUPPORTS_SPARSE_FILES,
FILE_SUPPORTS_REPARSE_POINTS, FILE_SUPPORTS_REMOTE_STORAGE,
FILE_SUPPORTS_OBJECT_IDS and FILE_SUPPORTS_ENCRYPTION.
Add several reparse point defines and typedefs for REPARSE_DATA_BUFFER,
REPARSE_GUID_DATA_BUFFER and REPARSE_POINT_INFORMATION.
* 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.
* libc/stdlib/rand.c (rand): Added __extension__ qualifier
to long long constant.
and `RegLoadKeyA'.
* registry.cc (get_registry_hive_path): New function.
(load_registry_hive): Ditto.
* security.cc (convert_sid_to_string_sid): New function.
(get_ssid): Renamed to `convert_string_sid_to_sid'.

(get_world_sid): Ditto.
* shared.h: New prototypes for `get_registry_hive_path' and
`load_registry_hive'.
* spawn.cc (spawn_guts): Set child->psid to NULL to force calling
`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
and to correct user environment in case user context changes.
(uinfo_init): Call internal_getlogin only if myself->psid is NULL,
that is user context changes.
* winsup.h: Add prototypes for `convert_sid_to_string_sid',
`convert_string_sid_to_sid' and `get_pw_sid'.
