      - remove sgml mode
      - automatically generate gi.types (needs GTK-Doc 1.19)
      - fix https://bugzilla.gnome.org/show_bug.cgi?id=700025
[WIP] - rearange sections a bit
[WIP] - add gi-building, gi-programming sections

3bcc0e43c6 girffi: Fix g_callable_info_prepare_closure for certain callables
Namely, those that are methods and those that throw GErrors.
We have very similar code in two places that calculate arg lengths and
argument types to stick into libffi. Merge, clean up, and correct both.

c99df8f34c ffi: Treat enums as 32 bit signed values to fix PPC64
To call a function dynamically using ffi, the caller
first has to tell ffi the size of all the input arguments
of the function. On little endian architectures (like x86_64)
specifying a size that's too large will happen to work because
of how the bits are laid out in memory.  On big endian architectures,
however, specifying the wrong size can lead to reading the wrong
bits.

The function g_type_info_get_ffi_type maps input giargument types to
specific sizes. It was assuming enums were word (pointer) sized; in
fact they can be in theory any size (1,2,4,8 bytes), but in practice
in introspection (via GIArgument) as well as GValue we're limited to 4
byte enums.

This commit fixes PPC64 (big endian, 64 bit).

g_callable_info_prepare_closure() allocates memory for the argument
types in the ffi_cif, so we need to free it.

3a310fd242 Don't include machine-dependent integral types in the typelib
Previously we had both e.g. GI_TYPE_TAG_LONG and GI_TYPE_TAG_INT64,
but in fact the typelib is already machine-specific, so it makes sense
to just encode this as a fixed type.  The .gir remains abstract.

We also remove size_t from the typelib; one would never want to treat
it differently than an integer.

time_t is removed as well; while bindings like gjs had special handling
to turn it into e.g. a JS Date object, I don't think we should encourage
people to use these POSIX types in their API.  Use GTimeVal or the like
instead.

Because the typelib is now really machine-specific, we need to remove
the -expected.tgirs from git.  (We could potentially add a check
which wasn't just a literal diff later)

9d2fd90f0a Correctly use ffi_closure_alloc(), fixing mmap permissions error
This restores the reverted-commit ed8634d:

    g_callable_info_prepare_closure: handle mmap permissions error

    When SELinux or similar is active, a process may not be able to mmap()
    a segment that is both writable and executable, which would causing
    g_callable_info_prepare_closure() to fail. Libffi has a workaround for
    this problem though (it maps the same non-anonymous region twice, once
    writable and once executable, and returns two separate pointers to
    it), so use that.

But with an added fix, when using ffi_closure_alloc(), we need to use
ffi_prep_closure_loc() so we can pass in the executable address of the
trampoline separately from the writable address, rather than the
deprecated ffi_prep_closure().

f2f0625622 [girffi] Clean up API, add g_function_info_prep_invoker
Rather than having bindings use g_function_info_invoke, which is basically
a toy/demo API, export a convenience utility function which takes the introspection
information and sets up things we need to pass to libffi.

Then invocation can be done directly to libffi by a binding.

As part of this work, remove some (unused by gjs) public functions from the
girffi API, and instead export a function to map to libffi which can work
semi-correctly.

d041deae59 Split g_ir_ffi_get_ffi_type() out from ginvoke.c
Extract a function to convert GITypeTag to ffi_type from the internals
of ginvoke.c. This will be useful in figure out structure alignment.

Also fix handling of gsize and time_t to be portable. (Add a check
to configure.ac to figure out the width of time_t.)
