041a5c5811 Parse headers outside of constructor 
In several cases, the parser would parse a header
(say, a track header, or the segment info header)
in the constructor for the type.  The parser had
assumed (incorrectly) that the file was well-formed,
but this turned out to be an incorrect assumption.

The parse errors triggered some assertion failures,
but this is not acceptable in a production system.

The parser solved that problem by separating the
construction of the header object from the parsing
of the file.  There is now a separate parse method
to be called after construction of the object,
which returns a status whether the parse was
successful.

This change fixes the bugs from the following
tracker issues:

6fa7c7611c Block parsing is now robust 
Previously, parsing of a Block element was done inside its
constructor.  Parsing errors were handled via assertion checks,
but this only works in practice if there are no actual errors
in the file.

We did come across a file, however, that used EMBL-style lacing,
but the lacing was done incorrectly and so the parse asserted.
This isn't acceptable for a production system, and more a graceful
handling of parse errors was needed.

The code was restructured such that the Block object's ctor does
only trivial initialization of member variables.  A separate Parse
method was added, that is called after the object is constructed.
If the parse succeeds all is well, otherwise the object is destroyed
and the error is reported to the caller.

This commit fixes bug tracker issue #398, described here:

4affedd0a7 Add support for encryption elements. 
Added support for the ContentEncoding element to be added to a
Track element for muxing. Currently only one ContentEncoding may
be added. The ContentEncoding must be encryption of the whole
frame with AES.
Added support for parsing the ConentEncoding elements. Currently
the parser does not parse any ContentCompression elements.
