libgmp: Upgrade to version 5.0.2
The GNU Multiple Precision Arithmetic Library is required for gcc44 and
all newer gcc compilers. It's alway been built with the "generic" C

gmp with a base set of assembly for x86 and x86_64, and even use
more processor-specific assembly if CPU_TYPE is set, but implementing that
will require some more work and a lot of testing. So for now, gmp is
still built with the much slower (but more portable) C files.
BUGS FIXED
===================
1. Fat builds fixed.
2. Fixed crash for huge multiplies when old FFT_TABLE2 type of parameter
selection tables' sentinel was smaller than multiplied operands.
3. The solib numbers now reflect the removal of the documented but
preliminary mpn_bdivmod function; we correctly flag incompatibility
with GMP 4.3.
4. Many minor bugs related to portability fixed.
5. The support for HPPA 2.0N now works, after an assembly bug fix.
6. A test case type error has been fixed. The symptom of this bug
was spurious 'make check' failures.
SPEEDUPS
===================
1. Multiplication has been overhauled:
(1) Multiplication of larger same size operands has been improved with
the addition of two new Toom functions and a new internal function
mpn_mulmod_bnm1 (computing U * V mod (B^n-1), B being the word
base. This latter function is used for the largest products,
waiting for a better Schoenhage-Strassen U * V mod (B^n+1)
implementation.
(2) Likewise for squaring.
(3) Multiplication of different size operands has been improved with
the addition of many new Toom function, and by selecting
underlying functions better from the main multiply functions.
2. Division and mod have been overhauled:
(1) Plain "schoolbook" division is reimplemented using faster quotient
approximation.
(2) Division Q = N/D, R = N mod D where both the quotient and
remainder are needed now runs in time O(M(log(N))). This is an
improvement of a factor log(log(N))
(3) Division where just the quotient is needed is now O(M(log(Q))) on
average.
(4) Modulo operations using Montgomery REDC form now take time O(M(n))
(5) Exact division Q = N/D by means of mpz_divexact has been improved
for all sizes, and now runs in time O(M(log(N))).
3. The function mpz_powm is now faster for all sizes. Its complexity has
gone from O(M(n)log(n)m) to O(M(n)m) where n is the size of the modulo
argument and m is the size of the exponent. It is also radically
faster for even modulus, since it now partially factors such modulus
and performs two smaller modexp operations, then uses CRT.
4. The internal support for multiplication yielding just the lower n
limbs has been improved by using Mulders' algorithm.
5. Computation of inverses, both plain 1/N and 1/N mod B^n have been
improved by using well-tuned Newton iterations, and wrap-around
multiplication using mpn_mulmod_bnm1.
6. A new algorithm makes mpz_perfect_power_p asymptotically faster.
7. The function mpz_remove uses a much faster algorithm, is better tuned,
and also benefits from the division improvements.
8. Intel Atom and VIA Nano specific optimisations.
9. Multiplication of large numbers has indirectly been sped up through
better FFT tuning and processor recognition. Since many operations
depend on multiplication, there will be a general speedup.
10. Plus hundreds of smaller improvements and tweaks!
NEW FEATURES
===================
1. New mpz function: mpz_powm_sec for side-channel quiet modexp
computations.
2. New mpn functions: mpn_sqr, mpn_and_n, mpn_ior_n, mpn_xor_n,
mpn_nand_n, mpn_nior_n, mpn_xnor_n, mpn_andn_n, mpn_iorn_n,
mpn_com, mpn_neg, mpn_copyi, mpn_copyd, mpn_zero.
3. The function mpn_tdiv_qr now allows certain argument overlap.
4. Support for fat binaries for 64-bit x86 processors has been added.
5. A new type, mp_bitcnt_t for bignum bit counts, has been introduced.
6. More Core i3, i5 an Core i7 processor models are recognised.

kernel - reformulate the maxusers auto-sizing calculation
* Reformulate the maxusers auto-sizing calculation, which is used as a
basis for mbufs and mbuf cluster calculations. Base the values on
limsize (basically the lower of KVM vs physical memory).
* Remove artificial limits.
* This basically effects x86-64 systems with > 4G of ram, greatly
increasing the default maxusers value and related mbuf limits.

kernel - Fix spin-based msgports
* LWKT threads can use thread/IPI or spin-based message ports. The
default is thread-based. Spin-based ports had numerous problems which
would result in panics. This commit fixes those panics and makes the
spinlock version viable.
* However, currently there is no performance improvement so the default
is staying as it was.

kernel - Major MP work on kq and signal processing
* Remove the global kq_token and move to a per-kq and per-kqlist
pool token. This greatly improves postgresql and mysql performance
on MP systems.
* Adjust signal processing tokens to be per-LWP instead of per-PROC.
Signal delivery still utilizes a per-proc token but signal distribution
now uses a per-LWP token, which allows the trap code to only lock the
LWP when checking for pending signals.
This also significantly improves database performance.
* The socket code also now uses only its per-socket pool token instead
of kq_token for its kq operations. kq handles its own tokens.

Revert "libcrypt - install crypt.h header"
This reverts commit
b4ed82ece2b69f4a6711d35c5e42938dfc1d804c.
BSDs have libcrypt and the prototypes for its functions are in
<unistd.h>. The reason we had crypt.h installed for a while was
to make KDE link against libcrypt, due to a wrong check in KDE.
Unfortunately, at least one other package (chat/dircproxy)
assumed that if <crypt.h> exists, it would also find prototypes
for crypt() and friends there, which is not the case. So it
would crash on x86_64 due to defaulting to int as crypt()'s
return type (which is a pointer).
The check in KDE has been fixed since and it properly checks
for the presence of libcrypt:
https://bugs.kde.org/show_bug.cgi?id=247627
Hence this revert.

grep: Upgrade to version 2.9
Release 2.9 (2011-06-21) [stable]
Release 2.8 (2011-05-13) [stable]
Bug Fixes
===================
1. echo c|grep '[c]' would fail for any c in 0x80..0xff,
and in many locales.
E.g., printf '\xff\n'|grep "$(printf '[\xff]')" || echo FAIL
would print FAIL rather than the required matching line.
[bug introduced in grep-2.6]
2. grep's interpretation of range expression is now more consistent with
that of other tools. [bug present since multi-byte character set
support was introduced in 2.5.2, though the steps needed to reproduce
it changed in grep-2.6]
3. grep erroneously returned with exit status 1 on some memory allocation
failure. [bug present since "the beginning"]
4. grep no longer clobbers heap for an ERE like '(^| )*( |$)'
[bug introduced in grep-2.6]
5. grep is faster on regular expressions that match multibyte characters
in brackets (such as '[áéíóú]').
6. echo c|grep '[c]' would fail for any c in 0x80..0xff, with a uni-byte
encoding for which the byte-to-wide-char mapping is nontrivial. For
example, the ISO-88591 locales are not affected, but ru_RU.KOI8-R is.
[bug introduced in grep-2.6]
7. grep -P no longer aborts when PCRE's backtracking limit is exceeded
Before, echo
aaaaaaaaaaaaaab |grep -P '((a+)*)+$' would abort. Now,
it diagnoses the problem and exits with status 2.

Release 3.1 (2011-08-10) [stable]
Bug fixes
===================
diff no longer reports spurious differences merely because two entries
in the same directory have names that compare equal in the current
locale, or compare equal because --ignore-file-name-case was given.
Changes in behavior
===================
--ignore-file-name-case now applies at the top level too.
For example, "diff dir inIt" might compare "dir/Init" to "inIt".
New features
===================
diff and sdiff have a new option --ignore-trailing-space (-Z).
