...via unoidl-write and the new source-format registry provicers, instead of
using idlc to produce .urd files, regmerge to merge them into legacy .rdb files,
and unoidl-write to translate those to new UNOIDL .rdb files.
gb_UnoApi and gb_InternalUnoApi ctors take an additional argument now that is
the path (below $(SRCDIR)) of the source-format registry from which to obtain
UNOIDL entity definitions. It can either be an .idl file (in which case no
*_add_idlfiles calls should be used and the resulting .rdb will contain all the
entities from that one .idl file; used in some tests to conveniently define all
test-specific entities in a single file) or a directory denoting the root of an
.idl file tree (in which case *_add_idlfiles calls specify the entites to
include in the resulting .idl file). (In the first case, the generated .rdb
file needs to depend on that single .idl file, so the gb_UnoApiTarget ctor
contains a dependency on that additional argument, which happens, as a side
effect, to trigger rebuilds in the second, tree-based case when addition/removal
of .idl files in the tree causes updates of directory time-stamps.)
UnoApiPartTarget and all the dependency-tracking logic based on .urd files in
solenv/gbuild/UnoApiTarget.mk is gone. Generation of an .rdb file now depends
on its source registry (see previous paragraph) and all the .idl files specified
with *_add_idlfiles (in the second, tree-based case above).
A consequence of that is that gb_UnoApi_add_idlfile, -_nohdl, and -_noheader all
do the same now. I left them in for now anyway, maybe they become relevant
again when the use of cppumaker is changed to read directly from a source-format
registry instead of going via a .rdb registry.
The legacy tools idlc, regcompare, regmerge, and regview are still contained in
the URE or SDK for now.
cb344cd59e "Revert 'Looks like idlc resolved
typedefs inside sequence<...>'" is re-reverted as now "the current offapi.rdb is
generated via unoidl-write instead of idlc."
