Build lib/ with WARNS=6 by default.

Similar to libexec/, do the same with lib/. Make WARNS=6 the norm and
lower it when needed.

I'm setting WARNS?=0 for secure/. It seems secure/ includes the
Makefile.inc provided by lib/. I'm not going to touch that directory.
Most of the code there is contributed anyway.

Rename all symbols in libmp(3) to mp_*, just like Solaris.

The function pow() in libmp(3) clashes with pow(3) in libm. We could
rename this single function, but we can just take the same approach as
the Solaris folks did, which is to prefix all function names with mp_.

libmp(3) isn't really popular nowadays. I suspect not a single
application in ports depends on it. There's still a chance, so I've
increased the SHLIB_MAJOR and __FreeBSD_version.

Bump library versions in preparation for 7.0.

Ok'd by: kan

Pass BN_CTX to internal functions instead of allocating it internally.
This allows msqrt() to only call BN_CTX_new() once intead of many times.

Suggested and reviewed by: stefanf

Do not put BN_CTX structures on the stack, but instead allocate them
runtime using BN_CTX_new(). This is done since in OpenSSL 0.9.7e we
can only allocate BN_CTX on the stack by including an internal OpenSSL
header file, and in OpenSSL 0.9.8 BN_CTX is entirely opaque, so having
it on the stack is not possible at all.

This is done as preparation for OpenSSL 0.9.8b import.

Tested on: amd64 i386 ia64
Tested with: src/tools/regression/lib/libmp

Add missing shared library interdependencies.

Bump the shared library version number of all libraries that have not
been bumped since RELENG_5.

Downgrage WARNS level for GCC 3.4.x.

Add a reference to bn(3) for those looking for functional multiprecision
integer arithmetic.

Adjust for OpenSSL 0.9.7.

This compiles fine w/WARNS.

MAN[1-9] -> MAN.

Added new bsd.incs.mk which handles installing of header files
via INCS. Implemented INCSLINKS (equivalent to SYMLINKS) to
handle symlinking include files. Allow for multiple groups of
include files to be installed, with the powerful INCSGROUPS knob.
Documentation to follow.

Added standard `includes' and `incsinstall' targets, use them
in Makefile.inc1. Headers from the following makefiles were
not installed before (during `includes' in Makefile.inc1):

kerberos5/lib/libtelnet/Makefile
lib/libbz2/Makefile
lib/libdevinfo/Makefile
lib/libform/Makefile
lib/libisc/Makefile
lib/libmenu/Makefile
lib/libmilter/Makefile
lib/libpanel/Makefile

Replaced all `beforeinstall' targets for installing includes
with the INCS stuff.

Renamed INCDIR to INCSDIR, for consistency with FILES and SCRIPTS,
and for compatibility with NetBSD. Similarly for INCOWN, INCGRP,
and INCMODE.

Consistently use INCLUDEDIR instead of /usr/include.

gnu/lib/libstdc++/Makefile and gnu/lib/libsupc++/Makefile changes
were only lightly tested due to the missing contrib/libstdc++-v3.
I fully tested the pre-WIP_GCC31 version of this patch with the
contrib/libstdc++.295 stuff.

These changes have been tested on i386 with the -DNO_WERROR "make
world" and "make release".

Fixed spelling of rpow in rpow's prototype.

Add __FBSDID()s to libmp

Don't claim to be mp(3).

Fix markup and a couple of thinkos.

Rename mp.3 to libmp.3 since that's what all the other "library"
manual pages (e.g., libstand, libdisk) are called.

Add a manual page for the libmp interface. Some of the descriptions
great, but then again neither is the interface it's documenting.

Move SHLIB_MAJOR to below LIB and add a comment about why NO_WARNS is set.

Install the man page and add mp.h to INCS.

Add a manual page for the libmp interface. It isn't real great, but
then again neither is the interface it's documenting.

This is the traditional BSD libmp interface implemented in terms of
the OpenSSL BIGNUM interface. It is provided for compatibility only
and should not be used in new code.
