  doc: add editor configuration section with Vim and Emacs settings
  dxva2.h: include d3d9.h to define LPDIRECT3DSURFACE9
  avformat/utils: Drop unused goto label.
  doxygen: Replace '\' by '@' in Doxygen markup tags.
  cosmetics: drop some completely pointless parentheses
  cljr: simplify CLJRContext
  drawtext: introduce rand(min, max)
  drawtext: introduce explicit draw/hide variable
  rtmp: Use nb_invokes for all invoke commands

Conflicts:

@subsection Editor configuration
In order to configure Vim to follow Libav formatting conventions, paste
the following snippet into your @file{.vimrc}:
@example
" indentation rules for libav: 4 spaces, no tabs
set expandtab
set shiftwidth=4
set softtabstop=4
" allow tabs in Makefiles
autocmd FileType make set noexpandtab shiftwidth=8 softtabstop=8
" Trailing whitespace and tabs are forbidden, so highlight them.
highlight ForbiddenWhitespace ctermbg=red guibg=red
match ForbiddenWhitespace /\s\+$\|\t/
" Do not highlight spaces at the end of line while typing on that line.
autocmd InsertEnter * match ForbiddenWhitespace /\t\|\s\+\%#\@@<!$/
@end example
For Emacs, add these roughly equivalent lines to your @file{.emacs.d/init.el}:
@example
(setq c-default-style "k&r")
(setq-default c-basic-offset 4)
(setq-default indent-tabs-mode nil)
(setq-default show-trailing-whitespace t)
@end example
