This adds support for the new cdash API where arbitrary files can be
uploaded to the CDash server. This CDash API communicates via json
files so the json parser jsoncpp was added to the Utilities directory.

bda4f0b6 jsoncpp: Add headers to help CMake include in-source jsoncpp headers
a02fbec5 jsoncpp: Drop doxygen comments that cause Clang warnings
In each internal target directory we generate a "Labels.txt" file
containing labels for that target and its sources, but it uses an
internal format. In order to make the list of labels easier to
publish, use a json format and call it "Labels.json".
Since we now use jsoncpp headers, link CMakeLib to the jsoncpp library.
Add an option to set the mtime of entries in a tarball so that one can
create a tarball with a consistent content hash (e.g. MD5) for a given
set of files regardless of their current timestamps on disk. This will
be useful for submission of tarballs to CDash, which tracks content
hashes to avoid duplication.

The default target in XCode is the first one in the file.
In commit v3.1.0-rc1~286^2 (cmTarget: use a hash_map for cmTargets
typedef, 2014-06-10) the order of the targets stored in cmMakefile was
made non-deterministic instead of lexicographic. Teach the Xcode
generator to do its own sorting to restore a predictable order.
While at it, place ALL_BUILD first (as is done in VS IDE generators)
explicitly in the comparison function so that it is the default target
even if other targets sort earlier lexicographically (e.g. "AAA").
In commit v3.1.0-rc1~687^2~4 (cmTarget: Make the source files depend on
the config, 2014-02-13) an early termination case was added to the Xcode
generator. Fix handling of this case to actually abort all the
generation steps. Otherwise some of the later steps are attempted
without the preconditions normally established by earlier steps,
possibly leading to a crash.
Since commit v3.0.0-rc1~335^2~1 (eclipse: Add natures for Eclipse based
on enabled languages, 2013-08-29) CXX projects got only "ccnature", but
Eclipse itself also adds "cnature" when creating C++ projects. Fix this
by adding both for CXX projects.

The sweeping pattern change in commit 238dd2fb (Use insert instead of a
loop in some cases, 2014-11-22) accidentally changed the iterator range
used on the queue in cmCTestBuildHandler::ProcessBuffer. Instead of
ending at the iterator positioned at the next newline to populate
CurrentProcessingLine, it was changed to go to the end of the queue.
This causes the line to contain newlines and possibly be cut off in the
middle of a line. Fix this regression by restoring use of the proper
end-of-line position.
Specialize for std::map types to delete the second element from
the iterator. This is not quite general enough that it can
be used everywhere, because CMake inherits from std::map and
creates typedefs with custom comparison functors etc, which
can not use this algorithm.
Commit v3.1.0-rc1~297^2~5 (cmTarget: Drop 'head' argument from
GetSourceFiles, 2014-07-10) exposed a dormant bug in source file computation,
causing the test case to regress. After that commit, the source file
computation and caching finds an existing container of source files. Prior to
that patch, the GetSourceFiles method was called with either a null pointer
for the head cmTarget, or it was called with the this pointer. The
processSources method is eventually called, which normalizes the difference
between the null pointer and the this pointer for the head target. However,
the cache key depends on the actual pre-normalized pointer. The change in
that commit caused the entry to be found in the cache where it was not before,
which resulted in incorrect behavior.
Prior to that commit, the test case also fails if the GetSourceFiles overload
taking a vector<cmSourceFile*> is changed to normalize the head target at
the beginning of the method:
cmTarget const* head = head_ ? head_ : this;
Such a construct was correctly used in other locations where similar caching
was in place, before being removed in commit v3.1.0-rc1~310^2~25 (cmTarget:
Remove 'head' argument from GetLinkInformation, 2014-06-12), but is not
neccessary anymore.
Commit v3.1.0-rc1~674^2~2 (cmTarget: Cache the cmSourceFiles in
GetSourceFiles., 2014-04-05) introduced the caching, but fails the test case
for an unrelated reason. That unrelated error was introduced in
commit v3.1.0-rc1~688^2~5 (cmTarget: Allow any generator expression in
SOURCES property., 2014-03-18) and fixed in
commit v3.1.0-rc1~561^2~1 (cmTarget: Fix listing of source files at
configure-time., 2014-04-13).
All commits which fail the test case in the testable way do so when such a
cached version of the source files is found and returned at generate
time. In the test case, the cached content is populated at configure-time
through the use of the deprecated LOCATION property with CMP0026 OLD. The
cached content is an empty container for the bar target in the test case,
because its source file 'foo.cpp.o' is not known until generate-time. That
means that no source files are available to compute the link language and
the reported error is issued.
The actual problem is that the SourceFilesMap should be cleared after
configure time by cmTarget::ClearLinkMaps. Clear it there now.
