- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

Fix warnings found by -Wmising-variable-declarations.

This self-written compiler warning, which is hopefully going to be
committed into LLVM sources soon, warns about potentially missing
`static' keywords, similar to -Wmissing-prototypes.

- bin/pax: Move external declaration of chdname and s_mask into extern.h.
- bin/setfacl: Move setfacl.c-specific stuff out of setfacl.h.
- sbin/mount_fusefs: Remove char *progname; use getprogname().
- others: add `static' where possible.

Teach libdwarf about the DW_FORM_flag_present dwarf attribute, so
programs using libdwarf (such as ctfconvert) don't error out on files
containing the attribute.

Removed redundant -I. from CFLAGS and "yes" from WITHOUT_MAN.

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.

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.

Store accurate offset information in CTF data. A large number of
structs had incorrect member offsets, limiting dtrace's usefulness
when working with them. An example of incorrect info (struct
rtentry) from before this fix:

<1738> STRUCT rtentry (200 bytes)
rt_nodes type=1731 off=0
rt_gateway type=849 off=65280 <== WRONG, should be 8 * 96
rt_flags type=3 off=65344 <== wrong again, and so on..

Add a BSD licensed DWARF library for use by the DTrace clients.

The API for this library is deliberately different to the GPL'd
libdwarf to avoid licensing problems.
