Move extents.c to working in byte positions only; fix a bug, extent_detach()
src/ChangeLog addition:
2015-03-27 Aidan Kehoe <kehoea@parhasard.net>
Fix a small bug, extent_detach(); minimise needless char-byte
conversion, extents.c, sticking to byte positions in general in
this file.
* extents.c:
* extents.c (signal_single_extent_changed):
Pass byte endpoints to
gutter_extent_signal_changed_region_maybe(),
buffer_extent_signal_changed_region().
* extents.c (extent_detach):
Call signal_extent_changed() correctly, pass both extent endpoints
rather than just the byte and character variants of the start.
* extents.c (struct report_extent_modification_closure):
Do this in terms of byte positions.
* extents.c (report_extent_modification_mapper):
Use byte positions, only converting to characters when we are
definitely calling Lisp.
* extents.c (report_extent_modification):
Use byte positions in this API, move the byte-char conversion to
our callers, simplifying extents.c (it all now works in byte
positions).
* extents.h:
Update report_extent_modification's prototype.
* gutter.c (gutter_extent_signal_changed_region_maybe):
Use byte positions here, avoids needless byte-char conversion.
* gutter.h:
Update the prototype here.
* insdel.c:
* insdel.c (buffer_extent_signal_changed_region):
Implement this in terms of byte positions.
* insdel.c (signal_before_change):
* insdel.c (signal_after_change):
Call report_extent_modification() with byte positions, doing the
char->byte conversion here rather than leaving it to extents.c.
* insdel.h:
* insdel.h (struct each_buffer_change_data):
The extent unchanged info now describes bytecounts.

This directory contains a number of XEmacs dynamic modules. These modules can be loaded directly with the command 'M-x load-module'. However, the preferred method of loading a module is to issue a "(require 'module-name)" command to the Lisp interpreter. This will store information so that a later "(unload-feature 'module-name)" can succeed. To compile one of these modules, simply enter the desired directory, type 'configure', and then 'make'. If you are building the module for an installed XEmacs, then 'make install' will place the module in the appropriate directory for XEmacs to find it later (assuming you have permission to write to that directory). A subsequent 'load-module' or 'require' will then load the module, as described above. Each of these demonstrates different features and limitations of the XEmacs module loading technology. For a complete discussion on XEmacs dynamic modules, please consult the XEmacs Module Writers Guide, which can be found in the ../info directory. For those wanting to get started with module writing, please see the 'sample' directory. It contains two subdirectories: internal and external. The 'internal' subdirectory contains the framework needed to migrate some core piece of XEmacs functionality into code that can either be compiled into the core or built as a separate module. The 'external' subdirectory contains the somewhat simpler framework needed to build a module separately from XEmacs. These should be considered starting places for module writing.
