Matches the behaviour of Xlib - if you set DISPLAY to :0.1 but only have
one screen, closes connection and returns error.
This introduces a new connection error code:

Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=42304
I have added more xcb connection error states at xcb.h header.
Also I have removed global error_connection variable, and added
an interface that returns connection error state.
TBD:
I will segregate errors states in a separate header file and try to
provide more precise error states, in future. Also I will give patch
for libX11, in that patch xcb_connection_t::has_error will be passed
to default io handler of libX11. This value can then be used for
displaying error messages.

This function was intended to allow libX11 to fix a multi-threaded hang,
but the corresponding libX11 patch caused single-threaded apps to spin
sometimes. Since I've retracted that patch, this patch has no users and
shouldn't go into a release unless/until that changes.
This reverts commit 2415c11dec5e5adb0c17f98aa52fbb371a4f8f23.

In some circumstances using xcb_poll_for_event is suboptimal because
it checks the connection for new events. This may lead to a lot of
failed nonblocking read system calls.

This function is useful for dynamic language garbage collectors. Frequently
a GC cycle may run before you want to block wainting for a reply.
This function is also marginally useful for libxcb apps that issue
speculative requests (eg. xlsclients).

GenericEvent can be more than 32 bytes long. Ensure that the required data is
pulled off the wire and tack it onto the event.
Due to the structure of the xcb_generic_event_t, the data is appended AFTER
the full_sequence field.

Since extensions no longer provide type-specific XID-generation functions,
xcb_generate_id now forms part of the xcb client API, rather than the
extension API; move it from xcbext.h to xcb.h accordingly.

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).

Xlib-specific deprecation remains.

The installed headers can't be relying on the presence of the internal
config.h defines, and it was breaking the xcb build for me as well due to
config.h not being included early enough.
