19cafc6 test: Replace remaining sprintf with snprintf (Wladimir J. van der Laan)
0a17714 uint256: replace sprintf with HexStr and reverse-iterator (Wladimir J. van der Laan)
Tree-SHA512: 2ba1dd4d25e1cbfff4d67b2f483448aa7c34ab5c799cddd48ba5826e5fa6df425abe35e244aaf4c52db9fccfb4d2a25a14bb4597bf9d1fce95991f270da6bb26
Split up util.cpp/h into:
- string utilities (hex, base32, base64): no internal dependencies, no dependency on boost (apart from foreach)
- money utilities (parsesmoney, formatmoney)
- time utilities (gettime*, sleep, format date):
- and the rest (logging, argument parsing, config file parsing)
The latter is basically the environment and OS handling,
and is stripped of all utility functions, so we may want to
rename it to something else than util.cpp/h for clarity (Matt suggested
osinterface).
Breaks dependency of sha256.cpp on all the things pulled in by util.
