Remove encrypt, decrypt - replace by cipher() and cipher1()
Remove seek() - not well supported/tested, I want to redo with a new interface
once CTR and OFB modes become stream ciphers.
Rename resync to set_iv()
Remove StreamCipher::IV_LENGTH and add StreamCipher::valid_iv_length() to
allow multiple IV lengths (as for instance Turing allows, as would Salsa20
if XSalsa20 were supported).

This, I think, was what was causing the OpenSSL AES code to crash (without
a key being set, the rounds are unset and probably causes the code to loop
out past the end of an array somewhere).
Sadly, this also confirms that OpenSSL's AES is much faster than Botan's:
AES-128: 115.032 [core] 152.994 [openssl]
AES-192: 98.6724 [core] 130.087 [openssl]
AES-256: 86.6348 [core] 113.608 [openssl]
Definitely some improvement can be made there! :(

- rounding.h (round_up, round_down)
- workfactor.h (dl_work_factor)
- timer.h (system_time)
And update all users of the previous util.h

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).

integers where we manipulate values denominated in nanoseconds to avoid
overflow (2^64 nanoseconds = 584.55 years, aka long enough)

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).
