delangel 55b756f1cc First step in major cleanup/redo of VCF functionality. Specifically, now:
a) VCF track name can work again with 3.3 or 4.0 VCF's when specifying -B name,VCF,file. Code will read header and parse automatically the version. 
b) Old VCF codec is deprecated. Reader goes now direct from parsing VCF lines into producing VariantContext objects, with no intermediate VCF records. If anyone can't resist the urge to still input files using the old method, a new VCF3Codec is in place with the old code, but it will be eventually deleted.
c) VCF headers and VCF info fields no longer keep track of the version. They are parsed into an internal representation and will be output only in VCF4.0 format.
d) As a consequence, the existing GATK bug where files are produced with VCF4 body but VCF3.3 headers is solved.
e) Several VCF 4.0 writer bugs are now solved.
f) Integration test MD5's are changed, mostly because of corrected VCF4.0 headers and because validation data mostly uses now VCF4.0.
g) Several VCF files in the ValidationData/ directory have been converted to VCF 4.0 format. I kept the old versions, and the new versions have a .vcf4 extension.

Pending issues:
a) We are still not dealing with indels consistently or correctly when representing them. This will be a second part of the changes.
b) The VCF writer doesn't use VCFRecord but it does still use a lot of leftovers like VCFGenotypeEncoding, VCFGenotypeRecord, etc. This needs to be simplified and cleaned.

ebanks 6b5c88d4d6 The GATK no longer writes vcf3.3; welcome to the world of vcf4.0. Needed to fix a few output bugs to get this to work, but it's looking great. Much more still to come. Guillermo: hopefully this doesn't break your local build too badly.

delangel b6bdd61283 a) Fix bug when multi-base reference is homopolymeric when writing a VCF4.0 variant context: computation of number of trailing bases was incorrect and we ended up with incorrect position.
b) Updated VCF4WriterTestWalker to take either VCF3 or VCF4 as inputs (this walker can also be used to convert from 3.3 to 4.0).

delangel 3ca2b7374b Fixes to better deal with the "Type" and "Number" field in the INFO and FORMAT header lines in VCF4.0. We now record these fields and provide appropriate conversions. This is the first version that passes fully the VCF validator.
Also, moved the flag indicating VCF4.0 to the VCFWriter constructor.

delangel ed71e53dd4 1) Initial complete version of VCF4 writer. There are still issues (see below) but at least this version is fully functional. It incorporates getting rid of intermediate VCFRecord so we now operate from VariantContext objects directly to VCF 4.0 output.
See VCF4WriterTestWalker for usage example: it just amounts to adding
vcfWriter.add(vc,ref.getBases()) in walker.

add() method in VCFWriter is polymorphic and can also take a VCFRecord, lthough eventually this should be obsolete.
addRecord is still supported so all backward compatibility is maintained.

Resulting VCF4.0 are still not perfect, so additional changes are in progress. Specifically:
a) INFO codes of length 0 (e.g. HM, DB) are not emitted correctly (they should emit just "HM" but now they emit "HM=1").
b) Genotype values that are specified as Integer in header are ignored in type and are printed out as Doubles.

Both issues should be corrected with better header parsing.

2) Check in ability of Beagle to mask an additional percentage of genotype likelihoods (0 by default), for testing purposes.
