The current code has issues when sizeof(long) <> sizeof(size_t). The two
types are assumed to be interchangeable and them being different will
cause crashes and endless loops.
This fix limits the maximum chunk size for many of the symmetric ciphers
to 2^30 bytes. This chunk size limits the amount of data that will
be encrypted/decrypted in one lump. The code internally handles block
of data later than the chunk limit, so this will present no difference
to the caller. Any loss of efficiency due to limiting the chunking to
1Gbyte rather than more should be insignificant.
Fixes Coverity issues:
1508498, 1508500 - 1508505, 1508507 - 1508527, 1508529 - 1508533,
1508535 - 1508537, 1508539, 1508541 - 1508549, 1508551 - 1508569 &
1508571 - 1508582.
