contrib/apr: Remove scope leak UB

In apr_vformatter, the variable buf was declared inside a limited scope
region, but a pointer to it is leaked outside of that region and used
later. This is undefined behavior. Fix by moving the buf variable to
function scope.

contrib/apr: Rip out bogus [CS]PRNG implementation

This construction used some relatively slow design involving SHA2; even if
it were fed real entropy (unclear; external to the design), it did not
handle fork in a safe way, and it was difficult to audit for correctness.
So just rip it out and use the very simple and known-correct arc4random(3)
interface in its place.

MFC r361677:

Change Makefiles under usr.bin/svn to make them easier to incrementally
update. No functional change intended.

MFC r361678:

Update apr to 1.7.0. See contrib/apr/CHANGES for a summary of changes.

MFC r361681:

Change more Makefiles under usr.bin/svn to make them easier to
incrementally update. No functional change intended.

apr: build some needed emulated 64-bit atomic bits after r361678

This should fix the build on armv{6,7}, mips, and mips64, which all need
emulated 64-bit atomics for apr.

MFC r361691:

Follow-up r361678 (update apr to 1.7.0) by also regenerating the apr
internal headers through the upstream configure script, with some minor
custom tweaks.

MFC r361692:

Update apr-util to 1.6.1. See contrib/apr-util/CHANGES for a summary of
changes.

Improve collation string and locales support

Merge collation support from Illumos and DragonflyBSD.

Locales are now generated with the new localedef(1) tool from CLDR POSIX files.
The generated files are now identified as "BSD 1.0" format.

The libc now only read "BSD 1.0" locales definitions, all other version will be
set to "C"
The localedef(1) tool has been imported from Illumos and modified to use tree(3)
instead of the CDDL avl(3)
A set of tool created by edwin@ and extended by marino@ for dragonfly has been
added to be able to generate locales and the Makefiles from the vanilla CLDR
unicode databases + a universal UTF-8 charmap (by marino@)
Update the locales to unicode v27
Given our regex(3) does not support multibyte (yet) it has been forced to always
use locale C
Remove now unused colldef(1) and mklocale(1)
Finish implementing the numeric BSD extension for ctypes
The number of supported locales has grown from 175 to 250 locales. Among the new
locales: 6 Arabic locales (AE EG JO MA QA SA), Different variations of spanish
locales.
Added new 3 components locales for mn_Cyrl_MN, sr_Cyrl_RS sr_Latn_RS,
zh_Hans_CN, zh_Hant_HK and zh_Hant_TW. Some aliases has been for 2 components
version when possible.

Thanks: Garrett D'Amore (Illumos) who made sure all his work was done under
BSD license!, Edwin Groothuis (edwin@) for the work he made on tools to be able
to generate locales definition usable in freebsd sources out of vanilla CLDR
definitions, John Marino (DragonflyBSD) who first merge the Illumos work into
Dragonfly and spent hours tracking down bugs.

Merge mpsutil(8) branch

mpsutil(8)/mprutil(8) are new utilities for managing LSI Fusion-MPT
2/3 controllers (mps(4) and mpr(4))

For now only informational commands have been implemented.

This utility has been written by scottl@ [1] and polished by myself[2]

Please note that from 3.5.0 onwards, clang, llvm and lldb require C++11
support to build; see UPDATING for more information.

Update serf-1.3.6 -> 1.3.7
Update subversion-1.8.9 -> 1.8.10

Security: CVE-2014-3504, CVE-2014-3522, CVE-2014-3528

Merge serf-1.3.6
+ Revert r2319 from serf 1.3.5: this change was making serf call handle_response
+ multiple times in case of an error response, leading to unexpected behavior.

Update serf 1.3.4 -> 1.3.5

Merge the projects/clang-sparc64 branch back to head. This brings in
several updates from the llvm and clang trunks to make the sparc64
backend fully functional.

Apart from one patch to sys/sparc64/include/pcpu.h which is still under
discussion, this makes it possible to let clang fully build world and
kernel for sparc64.

Any assistance with testing this on actual sparc64 hardware is greatly
appreciated, as there will unavoidably be bugs left.

Many thanks go to Roman Divacky for his upstream work on getting the
sparc64 backend into shape.

Update serf-1.3.0 -> 1.3.4 - fixes multiple issues (see the CHANGES file)
including an SSL issue that turned up in the cluster with svn-1.8.8.

Update serf 1.2.1 -> 1.3.0 for svn

Introduce svnlite so that we can check out our source code again.

This is actually a fully functional build except:
* All internal shared libraries are static linked to make sure there
is no interference with ports (and to reduce build time).
* It does not have the python/perl/etc plugin or API support.
* By default, it installs as "svnlite" rather than "svn".
* If WITH_SVN added in make.conf, you get "svn".
* If WITHOUT_SVNLITE is in make.conf, this is completely disabled.

To be absolutely clear, this is not intended for any use other than
checking out freebsd source and committing, like we once did with cvs.

It should be usable for small scale local repositories that don't
need the python/perl plugin architecture.

Import serf-1.2.1
