It includes a few policy changes (regarding what entropy is seeded when). Before this PR: * GetRand*: * OpenSSL * GetStrongRand*: * CPU cycle counter * Perfmon data (on Windows, once 10 min) * /dev/urandom (or equivalent) * rdrand (if available) * From scheduler when idle: * CPU cycle counter before and after 1ms sleep * At startup: * CPU cycle counter before and after 1ms sleep After this PR: * GetRand*: * Stack pointer (which indirectly identifies thread and some call stack information) * rdrand (if available) * CPU cycle counter * GetStrongRand*: * Stack pointer (which indirectly identifies thread and some call stack information) * rdrand (if available) * CPU cycle counter * /dev/urandom (or equivalent) * OpenSSL * CPU cycle counter again * From scheduler when idle: * Stack pointer (which indirectly identifies thread and some call stack information) * rdrand (if available) * CPU cycle counter before and after 1ms sleep * Perfmon data (on Windows, once every 10 min) * At startup: * Stack pointer (which indirectly identifies thread and some call stack information) * rdrand (if available) * CPU cycle counter * /dev/urandom (or equivalent) * OpenSSL * CPU cycle counter again * Perfmon data (on Windows, once every 10 min) The interface of random.h is also simplified, and documentation is added. This implements most of #14623. Tree-SHA512: 0120e19bd4ce80a509b5c180a4f29497d299ce8242e25755880851344b825bc2d64a222bc245e659562fb5463fb7c70fbfcf003616be4dc59d0ed6534f93dd20
2019-01-16Integrate util/system's CInit into RNGStatePieter Wuille
This guarantees that OpenSSL is initialized properly whenever randomness is used, even when that randomness is invoked from global constructors. Note that this patch uses Mutex directly, rather than CCriticalSection. This is because the lock-detection code is not necessarily initialized during global constructors.

2019-01-10util: Make ToLower and ToUpper take a charWladimir J. van der Laan
Unfortunately, `std::string` elements are (bare) chars. As these are the most likely type to be passed to these functions, make them use char instead of unsigned char. This avoids some casts.

2018-11-20Warn unrecognized sections in the config fileAkio Nakamura
In the config file, sections are specified by square bracket pair "[]"$, or included in the option name itself which separated by a period"(.)". Typicaly, [testnet] is not a correct section name and specified options in that section are ignored but user cannot recognize what is happen. So, add some log/stderr-warning messages if unrecognized section names are present in the config file after checking section only args.
