The ToCRLF/StringToCRLF functions are not very performance critical, but
we call it for each mail, and the current implementation is very
inefficient (mainly because it goes one byte at a time).
This patch replaces it with a better implementation that goes line by line.
The new implementation of ToCRLF is ~40% faster, and StringToCRLF is ~60%
faster.
