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.

ec81889c35 girepository: Fix some memory leaks in gdump.c
These were leaking memory when dumping introspection data from projects
for building their GIR files. That’s generally not a problem, unless
you’re trying to build the project with -fsanitize=address, which causes
the GIR build phase to error out due to leaking memory.

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).

Based on a patch by Simon Feltman.

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().

2825bd2edc build: Export Symbols Using Compiler Directives
Use compiler directives for exporting symbols for the build of
libgirepository and also for the test libraries, like what is now done
in GLib and GTK+ so that maintaining a separate .symbols (and .def files)
would not be needed, in which the correct compiler directive is determined
during configure time.  Drop all the .def files and the .symbols file as
we would not be using them anymore.

265ea792c1 girepository: Add Header for Version Macros
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.

cf4fb6a0fe g-ir-compiler: Add support for callback fields on GObjects
Use ParseState enum instead of a boolean for the ParseContexts embedded_type
flag. This allows specific tracking of the embedded type currently being
parsed which can now either be STATE_STRUCT_FIELD or STATE_CLASS_FIELD (or
allow for future expansion). Add ParseState::STATE_NONE as the default for
this field.

Fix GObject FieldBlob validation to take into account the sizeof
CallbackBlobs (copied from the struct validator).

Add static g_object_info_get_field_offset which parallels
g_struct_info_get_field_offset which is needed since callback fields may
vary in size.

f76e4ef683 typelib compiler: properly initialise memory
The typelib compiler was writing uninitialised memory to the output file.

There were two sources of this uninitialised memory: the hash writer included
some uninitialised memory in its output, and the bytes added after the hash
output for padding were also not being initialised.

Fix this by passing the padded size to the hash code writer function and
having that function initialise the entire memory region to zero before
writing.

c87579bbb6 giscanner: fix description field storage in .gir files
GTK-Doc description fields for tags can contain multiple lines and
even multiple paragraphs. Whitespace cannot be preserved in XML
attributes, so we move the "deprecated" description text into
a "<doc-deprecated />" element right next to where we already have
the "<doc />" element. Keep the "deprecated" attribute around for
backwards compatibility though, but set its value to "1" (analogous
to the "writable", "contruct", etc attributes) if the annotated
symbol is marked as deprecated.

While at it, add <doc-version /> and <doc-stability /> which
was not yet available in the .gir files...

This takes care of the "Since:", "Stability:" and "Deprecated:"
GTK-Doc tags. Nothing needs to be done for the "Returns:" tag as
as we already write a "<doc />" child element on "<return-value />".

33afebb2d7 Optimize g_irepository_find_by_gtype
When g_irepository_find_by_gtype() doesn't succeed on a simple prefix
match (the current 'fastpass' mechanism), it ends up taking a
considerable amount of CPU time, traversing the contents of all typelibs.

I imagine that the reasons to have the exhaustive search fallback are
not as strong as they used to be. For example, the case mentioned
(Clutter including Cogl) no longer seems to be true.

Also, typelibs (as generated by g-ir-scanner) now provide
comma-separated C prefix info for cases when the typelib includes
introspection info for multiple prefixes. For example, the Sugar typelib
has a c_prefix string of Sugar,EggSM,Gsm,Acme. So I imagine there are
not many remaining justified cases where the exhaustive search is needed.

With that in mind, I found two ways to optimize this function:

1. Support comma-separated C prefixes

2. Don't bother with an exhaustive search if we did find a typelib
   claiming support for the prefix. For example, if we're looking for
   GdkDeviceManagerXI2 (currently non-introspectable) and we already found
   typelib files providing the 'Gdk' prefix that didn't offer this, lets
   not bother with the exhaustive search, we aren't going to find anything.
