api_conv.pl: replace xcb_*_new with calls directly to xcb_generate_id, now that we have no type-safety XID wrappers.

After positive feedback from several people, we have decided to remove the XID
wrapper structures that attempted to provide C type safety, and replace them
with uint32_t typedefs.  Feedback has indicated that these type-safety hacks
generated more trouble than help.

We will bump the libxcb soname at the next release.

fix some indentation, remove args of the main function (not needed), xcb_sync -> xcb_aux_sync. Jamey, it seems that your script transforms XCBGetSetup into a type, instead of a function. Same for XCBSetupVendor. Maybe there are other fuctions that have the same problem.

update tutorial to the new api. Add some doc about cursors. Add some colors to section 6 (Opening and closing the connection to an X server). Tell me if you want to keep colors or not (colors can be modified in xcb.css)

subdirectory

We don't want to have to change the libxcb soname if we later manage to remove
the Xlib compatibility functions, and nothing except Xlib should ever use
them, so split them into a separate library.

In preparation for the repository split, move the relevant contents of the
top-level .gitignore into the .gitignore for each immediate subdirectory.

Rename API to follow a new naming convention:
* XCB_CONSTANTS_UPPERCASE_WITH_UNDERSCORES
* xcb_functions_lowercase_with_underscores
* xcb_types_lowercase_with_underscores_and_suffix_t
* expand all abbreviations like "req", "rep", and "iter"

Word boundaries for the names in the protocol descriptions fall:
* Wherever the protocol descriptions already have an underscore
* Between a lowercase letter and a subsequent uppercase letter
* Before the last uppercase letter in a string of uppercase letters followed
  by a lowercase letter (such as in LSBFirst between LSB and First)
* Before and after a string of digits (with exceptions for sized types like
  xcb_char2b_t and xcb_glx_float32_t to match the stdint.h convention)

Also fix up some particular naming issues:
* Rename shape_op and shape_kind to drop the "shape_" prefix, since otherwise
  these types end up as xcb_shape_shape_{op,kind}_t.
* Remove leading underscores from enums in the GLX protocol description,
  previously needed to ensure a word separator, but now redundant.

This renaming breaks code written for the previous API naming convention.  The
scripts in XCB's tools directory will convert code written for the old API to
use the new API; they work well enough that we used them to convert the
non-program-generated code in XCB, and when run on the old program-generated
code, they almost exactly reproduce the new program-generated code (modulo
whitespace and bugs in the old code generator).

The big change is treating numbers as separate "words" in the
translation, which leads to funny-looking names like xcb_char_2_b_t, but
makes more sense than the alternative in other situations and was
suggested on the mailing list.

This version still disagrees with Vincent's last proposed XSL, but I
think my output is now preferable. Hopefully Josh has been thinking
along the same lines.

(Some non-gnu makes, such as Solaris make, only recognize $< in implicit
 suffix rules, not explicit ones like this.)
