Makefile.in: Fixed bug with continuation line causing proto to fail.

             Added $(PROGS) $(SPROGS) as targets for make clean.
acconfig.h: Added HAVE_IRIX_SPECIFIC_CAPABILITIES.
configure.in: Added sys/capability.h header check.
              Added function checks for srandom random srand rand.
              Added HAVE_IRIX_SPECIFIC_CAPABILITIES test.
includes.h: Added #include <sys/capability.h>.
ntdomain.h: Moved struct acct_info into here from smb.h
smb.h: Added KERNEL_OPLOCK_CAPABILITY define.
       Moved enum action_type into rpcclient.h
       Moved struct cli_state into client.h
       Moved struct nt_client_info, struct tar_client_info, struct client_info
             into rpcclient.h
lib/genrand.c: Changed to use sys_random() & friends.
lib/smbrun.c: Lose capabilities after fork.
lib/system.c: Added set_process_capability(), set_inherited_process_capability()
              sys_random(), sys_srandom().
lib/util.c: Added Ander's EFBIG lock check to fcntl_lock for 64 bit access to an
            32 bit mounted NFS filesystem.
nmbd/nmbd.c: Changed to use sys_random() & friends.
nmbd/nmbd_browsesync.c: Changed to use sys_random() & friends.
passdb/ldap.c: Missed one pdb_encode_acct_ctrl call.
passdb/passdb.c: Changed to Ander's code for ' ' characters.
passdb/smbpass.c: Added Ander's code to reset ACB_PWNOTREQ.
script/mkproto.awk: Added 'long' to prototypes.
smbd/chgpasswd.c: Lose capabilities after fork.
smbd/open.c: Do the mmap *after* the kernel oplock.
smbd/oplock.c: Removed stub code from kernel oplock path.
               Added set_process_capability(), set_inherited_process_capability() calls.
smbd/reply.c: Initialize count = 0, offset = 0.
smbd/server.c: Added set_process_capability(), set_inherited_process_capability() calls.
tests/summary.c: Ensure we have RANDOM or RAND.
utils/smbpasswd.c: Added Ander's code to reset ACB_PWNOTREQ.
utils/torture.c: Changed to use sys_random() & friends.
