A copy of the xkbcomp sources (except the frontend) have been copied in
to provide a means to compile a XkbDescPtr. This definitely doesn't
build or do the right thing yet.
This avoids the BUILT_SOURCES weirdness and forcing the build into the
makekeys subdirectory. Added a new make variable KS_HEADERS that lists
all the keysym headers we're going to parse.
Following the kbproto convention, the headers will be named XKBcommon.h
and XKBcommonint.h. Furthermore, they'll be installed in X11/extensions
directory with the rest of the XKB headers.
Copies the code to initialize and destroy an XkbDescRec from libX11. The
original code is in
libX11/src/xkb/XKBAlloc.c
libX11/src/xkb/XKBGAlloc.c
libX11/src/xkb/XKBMAlloc.c
These are used throughout the XKB code, but are defined in XKBsrv.h,
which we'd like to avoid. Internal definitions for True/False have also
been added since they're in Xlib.h
Add the xkbcommon implementations of XKeysymToString and XStringToKeysym.
These symbols have the namespace prefix of Xkbc and are declared in
X11/XkbCommon.h.
The implementation is taken directly from Xlib, but does not include the
XKeysymDB parsing and hashing yet (if it ever will). A couple type
conversions were needed to keep from using Xlib.h. See original files:
libX11/src/KeysymStr.c
libX11/src/StrKeysym.c
The makekeys utility is used to generate the keysym hash tables during
the build. We try to detect a build machine native compiler so the
tables can be generated when cross compiling.
