Fix buildworld -DNO_CLEAN when using with Perforce, which marks files as

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.

Grammar fix.

Explicitly say that this is an internal library which is intended to be
used within FreeBSD base system only, and discourage user applications
from using it. User applications should use the expat version from the
ports/package collection.

Bump the version of all non-symbol-versioned shared libraries in
preparation for 8.0-RELEASE. Add the previous version of those
libraries to ObsoleteFiles.inc and bump __FreeBSD_Version.

Update the lib/expat tree for the new v2.0.1 expat import. The bsdxml.h
header is now in two parts: bsdxml.h and bsdxml_external.h, representing
the expat.h and expat_external.h headers. Updated the info on the man
page as well. Also, fixed a type-error in a printf in
sbin/ifconfig/regdomain.c that would cause a compiler warning.

Get endianess right.

Why would an XML library need to know about endianess anyway ??

been bumped since RELENG_5.

Stage 3 of dynamic root support. Make all the libraries needed to run
binaries in /bin and /sbin installed in /lib. Only the versioned files
reside in /lib, the .so symlink continues to live /usr/lib so the
toolchain doesn't need to be modified.

Minor tweaks to make this manpage readable.

Ok, concensus was to install libexpat under a "private brandname", and after
some deliberation the name "libbsdxml" was chosen since it conveys the two
most important attributes: "Private to FreeBSD" and "XML".

Add a skeleton man-page to give the credit and point for further
documentation. (If somebody wants to write a true mdoc manpage for
this I am sure both the eXpat people and I will be grateful).

Build libexpat out of src/contrib/expat.
