block-sha1: improve code on large-register-set machines

For x86 performance (especially in 32-bit mode) I added that hack to write
the SHA1 internal temporary hash using a volatile pointer, in order to get
gcc to not try to cache the array contents. Because gcc will do all the
wrong things, and then spill things in insane random ways.

But on architectures like PPC, where you have 32 registers, it's actually
perfectly reasonable to put the whole temporary array[] into the register
set, and gcc can do so.

So make the 'volatile unsigned int *' cast be dependent on a
SMALL_REGISTER_SET preprocessor symbol, and enable it (currently) on just
x86 and x86-64.  With that, the routine is fairly reasonable even when
compared to the hand-scheduled PPC version. Ben Herrenschmidt reports on
a G5:

 * Paulus asm version:       about 3.67s
 * Yours with no change:     about 5.74s
 * Yours without "volatile": about 3.78s

so with this the C version is within about 3% of the asm one.

And add a lot of commentary on what the heck is going on.

block-sha1: improved SHA1 hashing

Lookie here:

#             TIME[s] SPEED[MB/s]

nettle          1.591       383.6

notice? I outperform all the hand-tuned asm on 32-bit too. By quite a
margin, in fact.

Now, I didn't try a P4, and it's possible that it won't do that there, but
the 32-bit code generation sure looks impressive on my Nehalem box. The
magic? I force the stores to the 512-bit hash bucket to be done in order.
That seems to help a lot.

The diff is trivial (on top of the "rename registers with cpp" patch), as
appended. And it does seem to fix the P4 issues too, although I can
obviously (once again) only test Prescott, and only in 64-bit mode:

#             TIME[s] SPEED[MB/s]
rfc3174         1.662       36.73

linusas2       0.4487         136
mozilla        0.9704        62.9
mozillaas      0.9399       64.94

that's some really impressive improvement. All from just saying "do the
stores in the order I told you to, dammit!" to the compiler.

Documentation: git-send-email: correct statement about standard ports

The current documentation states that servers typically listen on port
465 and calls this "ssmtp". While it's true that many mail servers use
port 465 for SSL smtp, this is non-standard, and hails from the days
before smtp and submission TLS support, that arrived in RFC2487 and
RFC3207. Port 465 is actually assigned by IANA for unrelated purposes,

Express.

In any case, this patch helps the documentation better reflect both

that a user may wish to specify.

t8005: Nobody writes Russian in shift_jis

The second and third tests of this script expected that Russian strings
are converted between ISO-8859-5 and Shift_JIS in the "blame --porcelain"
format output correctly.

Sure, many platforms may convert between such a combination, but that is
only because one of the base character set of Shift_JIS, JIS X 0208,
defines codepoints for Russian characters (among others); I do not think
anybody uses Shift_JIS when seriously writing Russian, and it is perfectly
understandable if iconv() libraries on some platforms fail converting
between this combination, as it does not matter in reality.

This patch changes the test to verify Japanese strings are converted
correctly between EUC-JP and Shift_JIS in the same procedure.  The point
of the test is not about verifying the platform's iconv() library, but to
see if "git blame" makes correct iconv() library calls when it should.

We could instead use ISO-8859-5 and KOI8-R as the combination, because
they are both meant to represent Russian, in order to make this test
meaningful on more platforms, but we already use Shift_JIS vs EUC-JP
combinations to test other programs in our test suite, so this combination
is safer from the point of view of the portability.  Besides, I do not
read nor write Russian; sorry ;-)

git repack: keep commits hidden by a graft

When you have grafts that pretend that a given commit has different
parents than the ones recorded in the commit object, it is dangerous
to let 'git repack' remove those hidden parents, as you can easily
remove the graft and end up with a broken repository.

So let's play it safe and keep those parent objects and everything
that is reachable by them, in addition to the grafted parents.

As this behavior can only be triggered by git pack-objects, and as that
command handles duplicate parents gracefully, we do not bother to cull
duplicated parents that may result by using both true and grafted
parents.

git branch: fix performance problem

'git branch' looks at _all_ the refs, and verifies them.  Which means that
during cold-cache situations with a slow disk (and lots of tags, for
example) it can take several very annoying seconds (7.5s according to a
report by Carlos R.  Mafra).

This avoids most of it by simply doing the filtering before looking up
the commits, by using the "raw" version of for_each_ref.

git svn: fix shallow clone when upstream revision is too new

> git-svn uses $ra->get_latest_revnum to find out the latest
> revision, but that can be problematic, because get_latest_revnum

> useless).

Relying on SVN::Core::INVALID_REVNUM (-1) as the "start"
argument to SVN::Ra::get_log() proved unreliable with http(s)
URLs so the result of SVN::Ra::get_latest_revnum() is used as
the "start" argument instead.

do_one_ref(): null_sha1 check is not about broken ref

f8948e2 (remote prune: warn dangling symrefs, 2009-02-08) introduced a
more dangerous variant of for_each_ref() family that skips the check for
dangling refs, but it also made another unrelated check optional by
mistake.

The check to see if a ref points at 0{40} is not about brokenness, but is
about a possible future plan to represent a deleted ref by writing 40 "0"
in a loose ref when there is a stale version of the same ref already in
.git/packed-refs, so that we can implement deletion of a ref without
having to rewrite the packed refs file excluding the ref being deleted.

This check has to live outside of the conditional.
