Instead define a new function which returns a simple object which contains this information. This definitely breaks backwards compatability, though only with code that directly manipulates low level objects like BlockCipher*s directly, which is probably relatively rare. Also remove some deprecated accessor functions from lookup.h. It turns out block_size_of and output_size_of are being used in the TLS code; I need to remove them from there before I can delete these entirely. Really that didn't make much sense, because they assumed all implementations of a particular algorithm will have the same specifications, which is definitely not necessarily true, especially WRT key length. It is much safer (and probably simpler) to first retrieve an instance of the actual object you are going to use and then ask it directly.

This is a old vestigal thing from a class (SecureBuffer) that used this compile-time constant in order to store the values in an array. However this was changed way back in 2002 to use the same allocator hooks as the rest of the containers, so the only advantage to using the length field was that the initial length was set and didn't have to be set in the constructor which was midly convenient. However this directly conflicts with the desire to be able to (eventually) use std::vector with a custom allocator, since of course vector doesn't support this. Fortunately almost all of the uses are in classes which have only a single constructor, so there is little to no duplication by instead initializing the size in the constructor.

This is very different from STL's clear(), which is basically the equivalent to what is called destroy() in MemoryRegion. So to be able to replace MemoryRegion with a std::vector, we have to rename destroy() to clear() and we have to expose the current functionality of clear() in some other way, since vector doesn't support this operation. Do so by adding a global function named zeroise() which takes a MemoryRegion which is zeroed. Remove clear() to ensure all callers are updated.

Update all implementations. Add a new function parallel_bytes() which returns parallelism() * BLOCK_SIZE * BUILD_TIME_CONSTANT This is because i noticed all current calls of parallelism() just multiplied the result by the block size already, so this simplified that code. The build time constant is set to 4, which was the previous default return value of parallelism(). However the SIMD versions returned 2*native paralellism rather than 4*, so this increases the buffer sizes used for those algorithms. The constant multiple lives in buildh.in and build.h, and is named BOTAN_BLOCK_CIPHER_PAR_MULT.
