There are two copies of `StrLen` in the RapidJSON code base
 * strfunc.h: rapidjson::internal::StrLen<Ch>
 * unittest.h: Strlen<Ch>

To hide a warning on MSVC, align both implementations to use
'unsigned/SizeType' as return type and add an explicit cast.

Warning push/pop support has been added to GCC in version 4.6.0,
and pragmas to ignore certain warnings are present since 4.2.0.
This patch hides the compiler-specific warning push/pop/disable
pragmas behind a macro-based implementation (currently for MSVC and
clang /GCC.

This avoids warnings, as seen e.g. on GCC 4.4:
  ../../include/rapidjson/document.h:14: error: expected [error|warning|ignored] after ‘#pragma GCC diagnostic’
and earlier versions complaining about unknown pragmas being ignored.

Note: unittest.h and perftest.h need to check for compilers
explicitly, as rapidjson.h is not included there.

Added unit test for parsing EncodedStream to Document.

Also added documentation, unit tests for swapping Document/Value,
Document/Document.

The previous optimization #32 has problem that restoration requires
assignment operator.
Change the backup/restore process using a template wrapper class to
select code path.

The modification is slightly different from dlbattle123 to improve
speed.

‘>>’ should be ‘> >’ within a nested template argument list

An unit test is added

Can write d.Parse(...) instead of d.Parse<0>(...)
Hope to reduce strangeness and confusion for beginner.

This commit adds some simple tests for the deep-copying
of values, either based on the explicit constructor, or
the CopyFrom function.

It uses the CrtAllocator to test for possible double-free
errors due to insufficient copying.

The original FindMember() may access out-of-bound of the 'const char*
name' parameter.
This commit firstly follows
https://github.com/pah/rapidjson/commit/f86af8c232dc280ae510b119018d66ca08b82312

However, this must incur an StrLen() for name. A better API is by using
Value as the name, which provides the length of string internally. So a
set of new API are added:

operator[](const GenericValue& name)
FindMember(const GenericValue& name)
RemoveMember(const GenericValue& name)

During refactoring, it also adds an API:

RemoveMember(MemberIterator m)

which can be used for other purpose, such as removing a member while
iterating an object.

Fixes #7

tmpnam() in VS prepends backslash in the path.
