If one thread got SIGSEGV, function sigsegvHandler() would be triggered,
it would call bioKillThreads(). But call pthread_cancel() to cancel itself
would make it block. Also note that if SIGSEGV is caught by bio thread, it
should kill the main thread in order to give a positive report.

Rather than blindly evicting until maxmemory limit is achieved, this
update adds a time limit to eviction. While over the maxmemory limit,
eviction will process before each command AND as a timeProc when no
commands are running.
This will reduce the latency impact on many cases, especially pathological
cases like massive used memory increase during dict rehashing.
There is a risk that some other edge cases (like massive pipelined use
of MGET) could cause Redis memory usage to keep growing despite the
eviction attempts, so a new maxmemory-eviction-tenacity config is
introduced to let users mitigate that.

This commit makes stream object returning "stream" as encoding type in OBJECT ENCODING subcommand and DEBUG OBJECT command.
Till now, it would return "unknown"

This is a catch-all test to confirm that that rewrite produces a valid
output for all parameters and that this process does not introduce
undesired configuration changes.

THP can also be set to madvise, in which case it shouldn't cause
problems for Redis since redis (or the allocator) doesn't use madvise
to activate it.

There was a bug. Although cluster replicas would allow read commands,
they would not allow a MULTI-EXEC that's composed solely of read commands.
Adds tests for coverage.

Fix issues with writeConn() which resulted with corruption of the stream by leaving an extra byte in the buffer. The trigger for this is partial writes or write errors which were not experienced on Linux but reported on macOS.
