COMPRESS-407 - Validate Block and Record Sizes and use 512 blocks if none
given.
This PR includes the commits for COMPRESS-405 and COMPRESS-406.
The new content is

if cherry-picking.
The rest of the block size changes will be all be based on here, since they
become less separable

COMPRESS-405 Create Fixed Length Block OutputStream / WriteableByteChannel
This commit provides a new class that is an OutputStream and
WritableByteChannel, and which supports writing to a destination output stream
or byte channel in fixed size blocks. Internally, all writes are made using NIO.
If the destination is a FileOutputStream the existing channel is used.
Other OutputStreams are wrapped with a custom channel implementation which
does not attempt to split writes into chunks.
If the target channel fails to write the entire buffer in a single call, an
exception is thrown,
Incoming data is accumulated in a ByteBuffer until a complete block is
ready, then written to the target.
If WritableByteChannel::write(ByteBuffer) method is called, the code will
attempt to avoid copying data into the buffer if the buffer is empty, and a
complete block is available.
The class and UnitTest are in compress/utils . This is a MINOR change -
thus the version number for the package should be increated to 1.15.0.

COMPRESS-407 Validate Block and Record Sizes
Require block size >=0 that is multiple of 512 bytes.
Use block size of 512 if one is not given.
Require record size of 512 bytes. Deprecate constructors taking recordSize
as parameter
Modify tests to check for enforcement of record size == 512
Modify tests to check for correct overall length for
different block sizes including PAX default, USTAR default, and unspecified.
