GetObject and GetMutableObject are similar to GetRoot and GetMutableRoot,
and can be useful when wanting to access data that has just been created.
Unfortunately there is a danger in using these methods, as it is possible
that the buffer reallocates which will invalidate the pointers.
CreateUninitializedVector was performing the following actions:
1. call StartVector.
2. call make_space, and set buf to point to the reserved space.
3. call EndVector.
The problem is that a call to EndVector can ultimately call make_space, which
if the buffer is full, will cause a reallocation, invalidating the value stored
in buf. So setting buf needs to be delayed until after EndVector.
The following code, when run under valgrind shows a write to free'd memory before
the change, but no such error after:
int main()
{
flatbuffers::FlatBufferBuilder fbb(128);
char *buf = nullptr;
fbb.CreateUninitializedVector(128, &buf);
*buf = 0;
}
This overflow could allow malformed FlatBuffers to pass the verifier.

Bug: 27903580
To support the use case described in issue google/flatbuffers#3826, a new command line option --gen-name-strings
has been added, which will cause a static GetFullyQualifiedName function to be added
to the C++ output for tables/structs.
This is the first step in RPC support. Actual code generation
to follow.

Bug: 20122696
Adding an API reference for the supported languages.
General docs cleanup, including a new `tutorial` section that
supports all of the supported languages.
Added samples for each supported language to mirror the new
tutorial page.
Cleaned up all the links by making them `@ref` style links,
instead of referencing the names of the generated `.html` files.
Removed all generated files that were unnecessarily committed.
Also fixed the C# tests (two were failing due to a missing file).
Bug: b/25801305
Tested: Tested all samples on Ubuntu, Mac, and Android. Docs were
generated using doxygen and viewed on Chrome.

Cleaned up a few warnings to allow VS2012 to compile idl_parser and idl_gen_text (for exporting binary protobuf blobs as JSON) cleanly under static analysis.
Added a check for a preprocessor definition that can be set if the platform you're building for doesn't support any notion of absolute path resolution/realpath()/etc.
This is implemented as a template function, since Table::CheckField
is not reachable by subclasses of Table (private base class).

Bug: 26273432
This to allow the code to run on a greater range of build
configurations (that don't allow exceptions/RTTI).
If anyone ever doubts the usefulness of exception handling,
please show them this commit.
