the original font of the HD44780 with European character set, but includes
only characters from ISO 8859-1 and has been extended with bar graph and icons.
The t6963 driver now has its size to be configured in pixels! The size in
characters is automatically calculated based on the cell size. This makes
internal calculations more easy.
* Do not include system headers in shared files (stdlib.h).
* Don't include lcd.h only once in each driver.
* Remove some unnecessary headers from driver (e.g. syslog.h)
* Include <poll.h> instead of <sys/poll.h>
* Spelling fixes.
- Remove shared/str.h where not used.
- Remove shared/debug.h from all files as it has been completely replaced
by shared/report.h (it will be removed later).
- Add more doxygen comments to shared/* and clients/lcdproc/*.
- Include static functions in doxygen output.
