Several fixes for formatting bignums
* src/bignum.c: Include stdlib.h, for abs.
(bignum_bufsize, bignum_to_c_string): New functions.
* src/bignum.c (bignum_to_string):
* src/print.c (print_vectorlike): Use them.
* src/editfns.c (styled_format): Instead of having a separate
buffer for sprintf (which does not work for bignums), just append
to the main buffer. When formatting bignums, add support for the
standard integer flags -, #, 0, + and space. Fix some comments.
Capitalize properly when formatting bignums with %X. Use
functions like c_isdigit rather than reinventing the wheel.
Simplify computation of excess precision.
* src/print.c: Do not include bignum.h; no longer needed.
(print_vectorlike): Avoid recalculating string length.
* test/src/editfns-tests.el (format-bignum):
Test some of the above fixes.
