* Add ability to read and write rgba in bmp format, and
test in ioformats_reg.
* Add regression test prog/partition_reg.c
* Change the autotools library name from liblept to libleptonica,
to be consistent with the cmake library name. (Apologies to Jeff!)

ioformats_reg. Test new pixDisplayDiff() for visualizing diffs.
* Allow prog/concatpdf to output pdf with tiffg4 encoding and with
mixed tiffg4 and DCT encoding depending on image color content.

SelectRange() can depend slightly on platform.
* Convenience function for adding multiple black and white
borders.
* Fix oss-fuzz issue 42202: underined shift in
l_convertCharstrToInt().

interface allheaders.h, instead putting them in internal files
pix_internal.h, array_internal.h and ccbord_internal.h.
* Increase the .so number from 5.4.0 to 6.0.0.
* Rename the autotools generated libraries from liblept to
libleptonica
