open-vcdiff: add new recipe for version 0.8.3

This is Google's implementation of VCDIFF (RFC 3284) delta compression.
It's more flexible than Xdelta3 (as a developer point of view).

v2 patch:
State of bitbake world, Failed tasks 2014-03-29
reported a do_configure error:

| aclocal: error: non-option arguments are not accepted: '\'.

configure.ac file is quite out of date. Submitted patch upstream:
http://code.google.com/p/open-vcdiff/issues/detail?id=43
Note: autoupdate could be considered later...

+Fix this error:
+
+| aclocal: error: non-option arguments are not accepted: '\'.
+
+Starting from commit v1.11-662-g52246cc, when given non-option arguments, aclocal rejects them, instead of silently ignoring them.
+
+Declare ACLOCAL_AMFLAGS as a single line because autoreconf can't handle multiline.
+
+Notice that ACLOCAL_AMFLAGS is deprecated.
+In configure.ac, AC_CONFIG_MACRO_DIRS should be used (instead of AC_CONFIG_MACRO_DIR) but requires automake 1.13+.

+SUMMARY = "An encoder/decoder for the VCDIFF (RFC3284) format"
+DESCRIPTION = "A library with a simple API is included, as well as a \
+               command-line executable that can apply the encoder and \
+               decoder to source, target, and delta files. \
+               A slight variation from the draft standard is defined \
+               to allow chunk-by-chunk decoding when only a partial \
+               delta file window is available."
