'RELENG_4_1_0_RELEASE'.

This commit was manufactured to restore the state of the 4.1-RELEASE image.
Releases prior to 5.3-RELEASE are omitting the secure/ and crypto/ subdirs.

Simplify sytem call renaming. Instead of _foo() <-- _libc_foo <-- foo(),

2000-01-27T23:07:25+00:00

just use _foo() <-- foo().  In the case of a libpthread that doesn't do
call conversion (such as linuxthreads and our upcoming libpthread), this
is adequate.  In the case of libc_r, we still need three names, which are
now _thread_sys_foo() <-- _foo() <-- foo().

Convert all internal libc usage of: aio_suspend(), close(), fsync(), msync(),
nanosleep(), open(), fcntl(), read(), and write() to _foo() instead of foo().

Remove all internal libc usage of: creat(), pause(), sleep(), system(),
tcdrain(), wait(), and waitpid().

Make thread cancellation fully POSIX-compliant.

points.  For library functions, the pattern is __sleep() <--
_libc_sleep() <-- sleep().  The arrows represent weak aliases.  For
system calls, the pattern is _read() <-- _libc_read() <-- read().

Changed all paths to be relative to src/lib instead of src/lib/libc

1997-05-03T03:50:06+00:00

so that all these makefiles can be used to build libc_r too.

Added .if ${LIB} == "c" tests to restrict man page builds to libc
to avoid needlessly building them with libc_r too.

Split libc Makefile into Makefile and Makefile.inc to allow the
libc_r Makefile to include Makefile.inc too.

Guard against possible buffer overrun in filename passed.
Another candidate for 2.2.

Back out most of the last backout. :-) Guido removed the 1.1.1.1->1.1.1.2

changes from the vendor branch as well, backing the db-1.82 changes.

This file should now be the same as it was in rev 1.1.1.2.

Backout bzero patch.

Somehow, I also managed to get quite some other changes in this file at
the same time. All I did was checkout the file and  made a single change.
If someone has an explanation how these PURIFFY defines got in...

When freeing buffers in the db routines, also zeroize them

This should solve the bug where a coredumping ftpd reveals
encrypted passwords.
