- update to 6.10:
* Conversion of all entropy sources to use openssl instead of gcrypt, eliminating the need for the gcrypt library
* updated nist beacon entropy source to conform to version 2 of the
* Added rtlsdr radio entropy source
* Fixed arm host_cpu name, fixing a build break
* Fixed selection of default pkcs11 engine, based on target arch
* Moved closing jitter entropy source printouts to be LOG_DEBUG
* Typo fixes from codespell
* Fix a build break with power darn entropy sourceaa
* Improve interlock between main rngd thread, and jitterentropy threads during startup/shutdown to avoid deadlock/unneeded latency
* Avoid writing to write_wakeup_threshold when no specific threshold is set (allowing for separate services to preform this task without warnings from rngd)
* Enhance logging to more clearly indicate which entropy source is issuing a given log message
* Daemonize earlier, thereby avoiding early thread exit, which in turn leads to additional latency on shutdown
* Allow for immediate thread shutdown in jitter - By using sigsetjmp/siglongjmp, threads can exit, even when blocking in the jitter library
* Fixed texrels on on rdrand_asm.S for pic compilation
* allow use of libargp if libc lacks argp parsing
* explicitly link against -lcrypto, fixing build in pkcs11 entropy source
* replace pthread_yield with posix compliant sched_yield
* bias rngd to use faster sources of entropy when available, falling back to slower sources when needed
* Fix a shutdown delay resulting from a thread exit race
* Fix a few minor compilation warnings
* Fix make distcheck make target
* Minor typo fixes/cleanups
* Misc typo fixes
* Fixed build break on ppc
* Fixed bug in which getaffinity returns error on virt systems for jitterentropy
* Fixed low watermark sizing for kernel entropy pool
* Add a test mode, allowing entropy production rates to be measured
* Added jitter library as an entropy source
* Added short names to entropy sources (rather than just index numbers), for use in identifying sources to exclude/include/set options on
