up during the Fedora submission review, that each source file include some
text about the license. One handy Perl script later and each file now has
the line
Distributed under the terms of the Botan license
after the copyright notices.
While I was in there modifying every file anyway, I also stripped out the
remainder of the block comments (lots of astericks before and after the
text); this is stylistic thing I picked up when I was first learning C++
but in retrospect it is not a good style as the structure makes it harder
to modify comments (with the result that comments become fewer, shorter and
are less likely to be updated, which are not good things).

GostR3411_94_TestParamSet, this is compatible with the implementations in
Crypto++ and OpenSSL. This is not backwards compatible, though once the
implementation supports multiple param sets (which is required, unfortunately,
for compatability with various standards by CryptoCom, who have defined not
one but at least 4 (!!!) different sboxes to use with GOST), I may offer
Botan's previous sbox set as an option.
Since adding the GOST hash function (34.11) and signing algorithm (34.10)
are on the long term agenda (request by Rickard Bondesson, as the Russian
authorities want to use their local standards for their DNSSEC use), I
renamed the block cipher class (which had been just 'GOST') to GOST_28147_89
to minimize future name clashes.

replacing with an updated constructor to Algorithm_Factory taking a
vector of Engine*. The semantics of adding engines at runtime were not
defined nor very clear, it seems best to prohibit this unless and
until it is explicitly thought through (and until a need for it
presents itself).

algo_factory and algorithm_factory. This is confusing
so for consistency/simplicity, remove algo_factory, making
algorithm_factory the function to call.
In 1.7.14, several functions in lookup.h, including
retrieve_block_cipher, retrieve_hash, etc were changed to accept
a Library_State& reference. However it turns out with the
modified design I've settled upon for 1.8 that it is not
necessary to change those interfaces; instead they always refer
to the global_state algorithm factory which is exactly the
semantics one would expect/desire 99% of the time (and is source
compatible with code written for 1.6, also a plus)

was not the right place to keep track of this information. Also modify
all Algorithm_Factory constructor functions to take instead of a SCAN_Name
a pair of std::strings - the SCAN name and an optional provider name. If
a provider is specified, either that provider will be used or the request
will fail. Otherwise, the library will attempt best effort, based on
user-set algorithm implementation settings (combine with benchmark.h for
choosing the fastest implementation at runtime) or if not set, a static
ordering (preset in static_provider_weight in prov_weight.cpp, though it
would be nice to make this easier to toggle).

of algo_factory() several times, I decided to rename the functions.
algorithm_factory() just forwards to algo_factory as an inline.

selftests: off (if desired, run passes_self_test in selftest.h)
fips140: Just ran the self tests, totally bogus option.
use_engine: On by default (that is, if OpenSSL or asm code is compiled
in, it's used by default). One can get better control over this using
the provider feature of SCAN_Name (though this doesn't handle cases like
nested algorithms yet).
secure_memory: On by default.

This still is not an ideal split, since for SHA-1 we have both SSE2 and
x86/x86-64 asm. Currently we continue to punt to SSE2 if enabled, otherwise
asm, since the SSE2 seems to be the fastest thing going in my tests so far.
