configure.ac: Remove obsolete macros 
The newer macros that replace the obsolete ones are already present in configure.ac.

  * AC_PROG_LIBTOOL -> LT_INIT
  * AC_LANG_CPLUSPLUS -> AC_LANG([C++])

f95041faac lstmtraining: Fix handling of --max_iterations 
The iteration counter should be checked for each iteration,
not only at the end of a batch.

34efcd40be Fixed a resource leak detected by Coverity 
Replaced the inheritance relation of BLOCK and PDBLK by a member relation. This avoids the necessity of a virtual destructor in PDBLK for the occuring upcasts.

8f656e49bc training: Fix dubious parsing of command line 
- Don't support --helpshort as an undocumented alias for --help
- Don't allow any number of leading '-' characters.
  The preferred form uses --OPTION, and for compatibility reasons the new
  code still supports -OPTION.

Update also related documentation comments.

configure.ac: Check for the presence of pango 1.22.0 or higher 
Tesseract's training tool text2image uses these two functions: 
pango_glyph_item_iter_init_start
pango_glyph_item_iter_next_cluster

That means it requires Pango >=1.22.0:

708f55423b Add flag to build compiler options with G++ on macOS. 
Building with G++ on Darwin breaks when either AVX, AVX2, or SSE4.1
compiler option is set, unless G++ is actually CLANG.

This commit allows to build with G++, by asking G++ to delegate assembly
to the clang integrated assembler, instead of the GNU one.
