* support 3 types of end of line: Unix, Dos and old style Mac
* detect eol type automatically in detect_charset
* set buffer eol_type together with charset
* transparently convert eol sequence to \n upon reading buffers
characters in eb_nextc().
* transparently convert \n to eol sequence in eb_encode_uchar()
* handle eol types in convert-file-buffer-coding-system: either preserve
current value or force it via charset suffix -unix, -doc and -mac
* change read_charset() to accept eol_type suffix
* add eol_type and eol_char to CharsetDecodeState
* change charset methods to take CharsetDecodeState instead of charset pointers
* display eol_type in mode line if not unix
* use qe_mallocz for all structures
* prevent spurious uses of malloc/free/realloc
* pass pointers to pointers to all deletion functions
* use consistent patterns for list deletions
* add more dependencies in Makefiles
* styles_buffer hold static style info for each character in the buffer
* new buffer flags to create styles buffers with 1, 2 or 4 bytes per char
* copy static styles to the kill_ring and pasted them style enabled buffers
* preserve static styles in convert-buffer-file-coding-system
* display style bytes in bufed list
* add commands set-region-color, set-region-style, drop-styles
* org_scan_chunk: no longer checks for space before chunk
* org_colorize_line: better check for heading line
* org_colorize_line: check for chunks after white space
* simplify do_org_todo
* add new functions:
- do_org_mark_element (M-h)
- do_org_mark_subtree (C-c @)
* improve colorizer:
- handle blocks (with coloring for lisp src)
- handle TeX escapes, macros
- handle properties, wiki syntax for rich text
* simplify header line handling, and other such utility functions
* fix org-insert-heading, org-promote/demote, org-promote/demote-substree
* fix org-meta-return
* add org-move-subtree-up/down
* remove standard init_mode function
