Add jsoncpp in DEPS and the gyp file to build jsoncpp in chromium.

The jsoncpp is needed by libjingle as part of the webrtc effort. This patch probably not be the best solution as there's already one chrome json parser in base and another jsoncpp copy in native_client. However since the libjingle can depend on neither of them, here comes this patch. We hope to take this patch as a chance to get some advices on how should we handle this case.

+=head1 NAME
+
+licensecheck - simple license checker for source files
+
+=head1 SYNOPSIS
+
+B<licensecheck> B<--help>|B<--version>
+
+B<licensecheck> [B<--no-conf>] [B<--verbose>] [B<--copyright>]
+[B<-l>|B<--lines=>I<N>] [B<-i>|B<--ignore=>I<regex>] [B<-c>|B<--check=>I<regex>]
+[B<-r>|B<--recursive>] I<list of files and directories to check>
+
+=head1 DESCRIPTION
+
+B<licensecheck> attempts to determine the license that applies to each file
+passed to it, by searching the start of the file for text belonging to
+various licenses.
+
+If any of the arguments passed are directories, B<licensecheck> will add
+the files contained within to the list of files to process.
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<--verbose>, B<--no-verbose>
+
+Specify whether to output the text being processed from each file before
+the corresponding license information.
+
+Default is to be quiet.
+
+=item B<-l=>I<N>, B<--lines=>I<N>
+
+Specify the number of lines of each file's header which should be parsed
+for license information. (Default is 60).
+
+=item B<-i=>I<regex>, B<--ignore=>I<regex>
+
+When processing the list of files and directories, the regular
+expression specified by this option will be used to indicate those which
+should not be considered (e.g. backup files, VCS metadata).
+
+=item B<-r>, B<--recursive>
+
+Specify that the contents of directories should be added
+recursively.
+
+=item B<-c=>I<regex>, B<--check=>I<regex>
+
+Specify a pattern against which filenames will be matched in order to
+decide which files to check the license of.
+
+The default includes common source files.
+
+=item B<--copyright>
+
+Also display copyright text found within the file
+
+=item B<--no-conf>, B<--noconf>
+
+Do not read any configuration files. This can only be used as the first
+option given on the command-line.
+
+=back
+
+=head1 CONFIGURATION VARIABLES
+
+The two configuration files F</etc/devscripts.conf> and
+F<~/.devscripts> are sourced by a shell in that order to set
+configuration variables.  Command line options can be used to override
+configuration file settings.  Environment variable settings are
+ignored for this purpose.  The currently recognised variables are:
+
+=over 4
+
+=item B<LICENSECHECK_VERBOSE>
+
+If this is set to I<yes>, then it is the same as the B<--verbose> command
+line parameter being used. The default is I<no>.
+
+=item B<LICENSECHECK_PARSELINES>
+
+If this is set to a positive number then the specified number of lines
+at the start of each file will be read whilst attempting to determine
+the license(s) in use.  This is equivalent to the B<--lines> command line
+option.

+The JsonCpp library's source code, including accompanying documentation,

+In jurisdictions which do not recognize Public Domain property (e.g. Germany as of

+conditions of the MIT License (see below), or 3) under the terms of dual 
+Public Domain/MIT License conditions described here, as they choose.
+
+The MIT License is about as close to Public Domain as a license can get, and is
+described in clear, concise terms at:

+   http://en.wikipedia.org/wiki/MIT_License
+   
+The full text of the MIT License follows:

+
+The MIT license is compatible with both the GPL and commercial
+software, affording one all of the rights of Public Domain with the
+minor nuisance of being required to keep the above copyright notice
+and license text in the source code. Note also that by accepting the
+Public Domain "license" you can re-license your copy using whatever
+license you like.
