rand: introduce git_rand PRNG
Introduce `git_rand`, a PRNG based on xoroshiro256**, a fast,
all-purpose pseudo-random number generator: https://prng.di.unimi.it
The PRNG will be seeded by the system's entropy store when possible,
falling back to current time and system data (pid, uptime, etc).
Inspiration for this was taken from libressl, but since our PRNG is
not used for cryptographic purposes (and indeed currently only generates
a unique temp file name that is written in a protected directory),
this should be more than sufficient.
Our implementation of xoroshiro256** was taken almost strictly from
the original author's sources, but was tested against PractRand to
ensure that there were no foolish mistranslations:
```
RNG_test using PractRand version 0.94
RNG = RNG_stdin64, seed = unknown
test set = core, folding = standard (64 bit)
rng=RNG_stdin64, seed=unknown
length= 256 megabytes (2^28 bytes), time= 2.9 seconds
no anomalies in 210 test result(s)
rng=RNG_stdin64, seed=unknown
length= 512 megabytes (2^29 bytes), time= 6.2 seconds
no anomalies in 226 test result(s)
rng=RNG_stdin64, seed=unknown
length= 1 gigabyte (2^30 bytes), time= 12.7 seconds
no anomalies in 243 test result(s)
rng=RNG_stdin64, seed=unknown
length= 2 gigabytes (2^31 bytes), time= 25.4 seconds
no anomalies in 261 test result(s)
rng=RNG_stdin64, seed=unknown
length= 4 gigabytes (2^32 bytes), time= 50.6 seconds
no anomalies in 277 test result(s)
rng=RNG_stdin64, seed=unknown
length= 8 gigabytes (2^33 bytes), time= 104 seconds
no anomalies in 294 test result(s)
```

COPYING: remove regex copyright, add PCRE copyright
We now bundle PCRE for our regular expression implementation; include
that copyright notice and remove the now-unused regular expression
copyright.

openssl: dynamically load libssl and symbols (optionally)
Provide an interface around OpenSSL to dynamically load the libraries
and symbols, so that users can distribute a libgit2 library that is not
linked directly against OpenSSL. This enables users to target multiple
distributions with a single binary.
This mechanism is optional and disabled by default. Configure cmake
with -DUSE_HTTPS=OpenSSL-Dynamic to use it.

wildmatch: import wildmatch from git.git
In commit 70a8fc999d (stop using fnmatch (either native or
compat), 2014-02-15), upstream git has switched over all code
from their internal fnmatch copy to its new wildmatch code. We
haven't followed suit, and thus have developed some
incompatibilities in how we match regular expressions.
Import git's wildmatch from v2.22.0 and add a test suite based on
their t3070-wildmatch.sh tests.

COPYING: include winhttp definition copyright
Include the copyright notice from the deps/winhttp/ sources. Move the
LGPL to the bottom of the file (since multiple dependencies are LGPL
licensed) and include the actual copyright notices from the regex sources.

Replace pqueue with code from hashsig heap
I accidentally wrote a separate priority queue implementation when
I was working on file rename detection as part of the file hash
signature calculation code. To simplify licensing terms, I just
adapted that to a general purpose priority queue and replace the
old priority queue implementation that was borrowed from elsewhere.
This also removes parts of the COPYING document that no longer
apply to libgit2.

Cleanup legal data
1. The license header is technically not valid if it doesn't have a
copyright signature.
2. The COPYING file has been updated with the different licenses used in
the project.
3. The full GPLv2 header in each file annoys me.
