Currently uses coarse grained synchronized approach that seems to
create a lot of contention. This patch
- Uses a reentrant lock instead of synchronized monitor
- Switches to a condition variable based waiting rather than busy wait
- Removed synchronization for unnecessary fields

Depending on which compression codec is used, a short read of the
compressed bytes can cause catastrophic errors that confuse the WAL reader.
This problem can manifest when the reader is actively tailing the WAL for
replication. To avoid these issues when WAL value compression is enabled,
BoundedDelegatingInputStream should assume enough bytes are available to
supply a reader up to its bound. This behavior is valid per the contract
of available(), which provides an _estimate_ of available bytes, and
equivalent to IOUtils.readFully but without requiring an intermediate
buffer.
Added TestReplicationCompressedWAL and TestReplicationValueCompressedWAL.
Without the WALCellCodec change TestReplicationValueCompressedWAL will
fail.

When starting a jetty http server, one can explicitly exclude certain (unsecure)
SSL cipher suites. This can be especially important, when the HBase cluster
needs to be compliant with security regulations (e.g. FIPS).
Currently it is possible to set the excluded ciphers for the ThriftServer
("hbase.thrift.ssl.exclude.cipher.suites") or for the RestServer
("hbase.rest.ssl.exclude.cipher.suites"), but one can not configure it for the
regular InfoServer started by e.g. the master or region servers.
In this commit I want to introduce a new configuration
"ssl.server.exclude.cipher.list" to configure the excluded cipher suites for the
http server started by the InfoServer. This parameter has the same name and will
work in the same way, as it was already implemented in hadoop (e.g. for hdfs/yarn).

We introduced EnvironmentEdgeManager as a way to inject alternate clocks
for unit tests. In order for this to be effective, all callers that would
otherwise use System.currentTimeMillis() must call
EnvironmentEdgeManager.currentTime() instead, except the implementers of
EnvironmentEdge.

This bug was exposed by the test from HBASE-25924. Since this wal
implementations close the wal asynchronously, replication can potentially
miss the trailer bytes. (see jira comment for detailed analysis).
While this is not a correctness problem (since trailer does not have any entry data),
it erroneously bumps a metric that is used to track skipped bytes in WAL resulting
in false alarms which is something we should avoid.

Undo asserts that LZ4 and SNAPPY fails if their native libs are NOT
loaded; as of hadoop 3.3.1, LZ4 and SNAPPY can work w/o native libs.
