snprintf is a standard function which should be available
on all relevant platforms, so those checks are unnecessary.

It wrongly detects old versions of ICU as valid.
Checking with pkg-config is sufficient and also sets ICU_UC_LIBS.

The first usage of AC_CHECK_HEADERS must be unconditional,
otherwise configure fails to detect support for shared libraries.
This fixes a regression introduced by commit a07025c993.

* Use AS_HELP_STRING
* Use [] instead of () for default in help text
* Run AC_CHECK_HEADERS, AC_CHECK_LIB only if OpenCL support is enabled

Instead of defining the DISABLED_LEGACY_ENGINE macro in config_auto.h
(which is not included by all source files), define it as a preprocessor
option for those parts of the code which require it.

The tesseract/ subdirectory is no longer automatically added to the
include path of the compiler. Therefore old code which used code like
#include "capi.h"
must now change that to
#include "tesseract/capi.h"
This avoids name conflicts with header files from other projects.

Not only version names like 4.0.0, but also version names like
v4.0.0 or tesseract-4.0.0 are now supported and give the same
GENERIC_MAJOR_VERSION = 4.

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++])
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.
Commit f9157fd91d changed the rules for
the documentation, so make always tried to build it and failed if
asciidoc was missing since that commit.
Now configure tests whether asciidoc is available and builds the
documentation conditionally. It also reports that to the user.

That macro disables automated updates when configure.ac or a Makefile.am
changes. Normally those updates are wanted because users typically
forget running ./autogen.sh.

AX_SPLIT_VERSION only works after AM_INIT_AUTOMAKE, so that macro had
to be moved.
GENERIC_MAJOR_VERSION, GENERIC_MINOR_VERSION and GENERIC_MICRO_VERSION
are now set automatically and can be used in further processing.

While "echo -n" works on Debian GNU Linux, it fails to produce a valid
configure file on macOS, so try a different shorter solution.
