program: automatic verifier log sizing and ProgramInfo.RecursionMisses()
For the longest time users had to specify ProgramOptions.LogSize to get the
full verifier log for large programs. The library now automatically figures out
the correct buffer size to use and the field is deprecated. It will be removed
in the next version.
ProgramInfo now exposes how often a program didn't execute due to recursion
limits via RecursionMisses.
perf, ringbuf: better control over wakeups, Flush()
There is a trade off between how fast samples are processed and how much CPU is
used. Reading samples as quickly as possible uses more CPU, reading in batches
is cheaper.
It's now possible to configure a "maximum time before a wakeup" by using
Reader.SetDeadline(). This now guarantees that any pending samples are read
at the end of the deadline, even if the Watermark wasn't reached.
It's also possible to manually flush the buffer using Flush().
Bugfixes
The various Copy() methods now to a full deep copy and all accept nil values.
