7cdf5d0d1d build: enable -Wcast-function-type
Where it's easy add dummy args to match the cast; where the target is a subset just
prevent the warning with a cast to void*.

Provide a real copy function for the boxed type code in regress_foo.
This code is never executed afaics, but why not.

Except for the Python module because nothing in the CPython API is marked const
and we'd have to cast everywhere.

4dafb4d5cf girepository: Properly acquire and check pointer values
On Windows (Visual Studio at least), unsigned longs are always 4 bytes,
on both 32-bit and x64 Windows, so we cannot use unsigned longs to deal
with pointers on 64-bit builds, as pointers are 8 bytes on 64-bit
Windows, which may well render the pointer (which we acquired from
libffi) invalid.

This will fix crashes in PyGObject which are manifested when launching
the cairo-demo example sript (intermittent) and when clicking on
"Interactive Dialog" button in the Dialog demo in the PyGObject GTK+
Code demos before entering anything in Entry 1 and Entry 2, when running
on x64 Visual Studio builds of the GTK+/PyGObject stack.

Also use size_t instead of unsigned long in gthash.c when we check that
memory & 0x3 is 0, to silence compiler warnings from enabling /Wp64,
which is used to detect portability problems on Visual Studio when
doing x86->x64 code builds.

c01bc6ef0e g-ir-scanner: Don't require SRCDIR and BUILDDIR env vars
When building with Meson, we cannot set environment variables while
running custom targets and our builddir layout is different from
Autotools anyway.

Now g-ir-scanner and friends can autodetect when they're being run
uninstalled by Meson and will find _giscanner.so and the giscanner
python files in the build directory. This is very similar to what
gdbus-codegen uses in glib/gio.

Same for girepository/gdump.c.

5ecbc70a05 Increase MAX_NAME_LEN
There is no real limit on the length of an identifier, and some
toolchains easily hit the current limit of 200 characters.

According to this answer on StackOverflow, 2048 seems to be the limit on
MSVC and ICC:

8a08674b33 girepository: Merge overrides with the regular search path
This reverts commit e81c4681cc88a00fcd841c5a68d860d3714b55d7

The GI_TYPELIB_PATH envvar will still allow overriding the default
typelib dir (based on gobject-introspection libdir), but applications
will have the last say about typelib lookup directories. The resulting
lookup order is now:

- Paths added through g_irepository_prepend_search_path()
- Paths in GI_TYPELIB_PATH
- The default gobject introspection lookup dir

This makes g_irespository_prepend_search_path() work as announced
despite environment variables. If any application was relying on
GI_TYPELIB_PATH overriding the paths of this function call (for e.g.
make check, or to be able to run code inside the project tree), it
is encouraged to set up a similar envvar for their application specific
lookup dir, or perform this override through other means.

4e43ed8112 cmph/bdz.c: Work Around MSVC 2012 x64 Compiler Bug
Due to an MSVC 2012 x64 compiler issue, the compiler generates bad code
for bdz.c, so the for loop in assign() continues running until the point
i falls below zero, causing an access violation when we try to do
curr_edge=queue[i]; (line 427 in bdz.c).  Address this issue by breaking
out of the loop at the end of it when i reaches 0 after doing the
necessary processing.

These were leaking memory when dumping introspection data from projects

220fbf35b8 girepository: Use constant time calculation for sections after Object fields
Add "n_field_callbacks" to ObjectBlob which represents the number of object
fields which are also callbacks. This a allows a constant time computation
for accessing sections after fields. Track writing of this field by passing
an extra argument through the girnode writers recursive call structure. This
essentally reverts a portion of commit 7027bb256d0d1ab which added a linear
time computation for accessing sections after fields.
Update typelib validator to also ensure n_field_callbacks is properly set.

3fa183524e girepository: Remove "optimization" for found prefixes
This optimization is bugged and broken in the case of certain
libraries. GNOME uses a lot of prefixes with "G", so we'll almost always
have found the prefix.

This is specifically a problem for something like GXml.xDocument, which
uses a type name starting with a lower-case letter, which fools the
prefix logic, but we're also fooled by the "G" appearing in GLib and
Gio.

A more sophisticated version of this check would have three passes:
check prefix with type-case, check prefix without type-case, global
search, but this is an edge case and it doesn't feel worth it to write.

6eaa308869 girepository: Add g_struct_info_find_field()
Add find_field utility function for finding a field info by name.
Beyond convenience, this should be faster than manually using
the get_n_fields and get_field functions because get_field does
an additional iteration for each field to calculate offsets O(n^2).
Thus find_field combines the offset and comparison
computations into a single loop O(n).

e222ca2ef2 girepository: Add g_irepository_get_immediate_dependencies()
g_irepository_get_dependencies() is supposed to return the transitive
closure of all dependencies of the given namespace. However, it just
loads the dependencies field from the typelib, which is supposed to only
list immediate dependencies.

Introduce a new g_irepository_get_immediate_dependencies() which does
this, and rewrite g_irepository_get_dependencies() to build the
transitive closure of all its namespace dependencies. This does not
require loading any new typelibs, as the transitive closure of
dependencies should already have been loaded by g_irepository_require()
or g_irepository_load_typelib().

This adds a header to the girepository library, which is then included
either directly or indirectly by the other headers so that all the public
symbols (and the 2 symbols in gitypelib-internal.h used by the tools) are
decorated by a macro, that can later be used to export the symbols and also
to be used to display compile-time warnings for usage of deprecated APIs,
which is like what is now being done in GLib (and GTK+, Clutter, and so
on).

This marks the first step that we begin to stop depending on the .symbols/
.def files to export the symbols.
