- 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 unloading of libiconv module.

Previously it would either loop infinitely or exit with error leaking a lock.

Fix improper handling of variadic args with ICDEBUG

Add unicode support to msdosfs and smbfs; original pathes from imura,
bug fixes by Kuan-Chung Chiu <buganini at gmail dot com>.

Tested by me in production for several days at work.

Mark MALLOC_DEFINEs static that have no corresponding MALLOC_DECLAREs.

This means that their use is restricted to a single C file.

Switch to our preferred 2-clause BSD license.

Split tolower/toupper code from usual xlat16 kiconv table, and make it
possible to do tolower/toupper independently without code conversion.

Add simple locking for the in-kernel iconv code. Translation operations
do not need any locking. Opening and closing translators is serialized
using an sx lock.

Note: This depends on the earlier fix to kern_module.c to properly order
MOD_UNLOAD events.

MFC after: 2 months

Normalize a significant number of kernel malloc type names:

- Prefer '_' to ' ', as it results in more easily parsed results in
memory monitoring tools such as vmstat.

- Remove punctuation that is incompatible with using memory type names
as file names, such as '/' characters.

- Disambiguate some collisions by adding subsystem prefixes to some
memory types.

- Generally prefer lower case to upper case.

- If the same type is defined in multiple architecture directories,
attempt to use the same name in additional cases.

Not all instances were caught in this change, so more work is required to
finish this conversion. Similar changes are required for UMA zone names.

- Fix checking range of strings of struct iconv_add_in in libsmb and libkiconv,
- Add checking range of strings to iconv_sysctl_add().

Temporary restore a part of rev 1.6.
We must not increase a capability of buffer size here,
because codes which call these functions expect that dst and src
are the same size.
This will cause problem when someone convert a character whose
length is different between charsets on smbfs which was changed
to use xlat16 converter.

/* -> /*- for copyright notices, minor format tweaks as necessary

Convert the vfsconf list to a TAILQ.

Introduce vfs_byname() function to find things on it.

Staticize vfs_nmount() function under the name vfs_donmount().

Various cleanups.

- Support for multibyte charsets in LIBICONV.
- CD9660_ICONV, NTFS_ICONV and MSDOSFS_ICONV kernel options
(with corresponding modules).
- kiconv(3) for loadable charset conversion tables support.

Remove M_TRYWAIT/M_WAITOK/M_WAIT. Callers should use 0.
Merge M_NOWAIT/M_DONTWAIT into a single flag M_NOWAIT.

Fix a bunch of s/int */size_t */.

Convert GNU variadic macros to the ISO 9X variety.

Add function prototypes and base module for kernel side iconv library.
Add simple "xlat" converter which performs 8to8 table based conversion.
Unicode converter will be added in the near future.
