minibuf)

misc:
- add `eb_peekc(EditBuffer *b, int offset)`
- boolean cmdline options no longer require an argument, true if none provided
- int cmdline options either require an argument (CMD_LINE_INT_ARG) or take an
optional argument, value is incremented if argument is not provided.

qe_free_picture(QEPicture **ipp);
QE_PAL_MODE(r, g, b, incr)
int qe_picture_set_palette(QEPicture *ip, int mode,
unsigned char *p, int count, int tcolor);
int qe_picture_copy(QEPicture *dst, int dst_x, int dst_y, int dst_w, int dst_h,
const QEPicture *src, int src_x, int src_y, int src_w, int src_h,
int flags);
int qe_draw_picture(QEditScreen *s, int dst_x, int dst_y, int dst_w, int dst_h,
const QEPicture *ip,
int src_x, int src_y, int src_w, int src_h,
int flags, QEColor col);

some cosmetics, moved code
create files with mode 0644 in raw_save_buffer
untabified, removed redundant spaces
modified code generators to the same effect
- ctype.h has strong constraints on arguments
- ctype.h implements bogus irrelevant inefficient locale specific behaviour
- use replacement css_xxx functions
- all take int arguments: can be any value, yet only test ASCII subset
- all css_isxxx return true boolean (1 or 0)
- removed utoupper(int) -> css_toupper(int) has same functionality
