netsurf/beos/beos_scaffolding.cpp
François Revel 44856d86d4 Fix the BeOS build:
- hack to work around stdbool.h issue with R5 devkit
- fix prototypes
- fix bitmap code
- fix copy-paste on forward button
- remove unused gif throbber loading code
- R5 rgb_color doesn't have != operator, use memcmp()
- switch back to file based [beos]default.css for the time being
- realpath() hack for R5
Regressions:
- asserts on haiku-os.org
- no libns* yet, so less image support
- text field input doesn't work anymore.
