Subject: xlib/shm: Sanity check that the server handles XSendEvent with ShmCompletion
Uli Schlachter suggested it would be wiser to complement our blacklist
of known broken X/libXext with an explicit roundtrip to check for a
BadValue error return when we try to use XSendEvent.

Subject: type1-subset: parse all operators
The PDF at bug 56265 contained a Type 1 font that used the "div"
operator to compute the glyph width. As the "div" operator was
not handled by the charstring parser this resulted in an incorrect
glyph width in the PDF output.
Fix this by upgrading the charstring parsing to handle all Type 1
operators.

Subject: xlib/shm: Check for XShm headers
Not all version of libXext ship the same set of headers, so play safe
and check during configure that we have the headers we depend upon in
the code.

Subject: xlib/shm: Use shmstr.h instead of shmproto.h if available
Before it was known as shmproto.h, the wire protocol definition was to
be found in shmstr.h, so if we don't have the current version of libXext
try to use the older includes.

Subject: type1-subset, cff-subset: Plugged 2 memory leaks
- _cairo_type1_font_subset_fini doesn't free font->cleartext
- _cairo_cff_font_create can exit without freeing font->font_name and/or
font->data; _cairo_cff_font_load_opentype_cff is called to allocate
font_name, then _cairo_cff_font_load_cff is called to allocate
font->data, then _cairo_cff_font_load_cff's return status is checked
and if it failed, it jumps to fail1. This can cause font_name to leak
since the fail1 target only frees the font variable. In addition,
_cairo_cff_font_load_cff can fail -after- allocating data, and then
data won't be freed either.
