A decision was made [1] to no longer support Make in DPDK, this patch
removes all Makefiles that do not make use of pkg-config, along with
the mk directory previously used by make.

Start a new release cycle with empty release notes.
The ABI version becomes 21.0.
The ABI major is back to normal, having only one number (21 vs 20.0).
The map files are updated to the new ABI major number (21).
The ABI exceptions are dropped.
Travis ABI check is disabled because compatibility is not preserved.

Since the library versioning for both stable and experimental ABI's is
now managed globally, the LIBABIVER and version variables no longer
serve any useful purpose, and can be removed.
The replacement in Makefiles was done using the following regex:
^(#.*\n)?LIBABIVER\s*:=\s*\d+\n(\s*\n)?
(LIBABIVER := numbers, optionally preceded by a comment and optionally
succeeded by an empty line)
The replacement for meson files was done using the following regex:
^(#.*\n)?version\s*=\s*\d+\n(\s*\n)?
(version = numbers, optionally preceded by a comment and optionally

Extend existing cfgfile library with providing new API functions:
rte_cfgfile_create() - create new cfgfile object
rte_cfgfile_add_section() - add new section to existing cfgfile
object
rte_cfgfile_add_entry() - add new entry to existing cfgfile
object in specified section
rte_cfgfile_set_entry() - update existing entry in cfgfile object
rte_cfgfile_save() - save existing cfgfile object to INI file

dynamically build up a proper DPDK configuration, rather than having
to have a pre-existing one.

When parsing a ini file with a "key = value" line that has both "key" and
"value" sized to the maximum allowed length causes a parsing failure. The
internal "buffer" variable should be sized at least as large as the maximum
for both fields. This commit updates the local array to be sized to hold
the max name, max value, " = ", and the nul terminator.

The call to memchr() uses the absolute length of the string buffer instead
of the actual length of the string returned by fgets(). This causes the
search to go beyond the '\n' character and find ';' characters in random
garbage on the stack. This then causes the 'len' variable to be updated
and the subsequent search for the '=' character to potentially find one
beyond the first newline character.
Since this bug relies on ';' and '=' characters appearing in random places
in the 'buffer' variable it is intermittently reproducible at best.

The current cfgfile comment character is hardcoded to ';'. This commit a
new API to allow the user to specify which comment character to use while
parsing the file.
This is to ease adoption by applications that have an existing
configuration file which may use a different comment character. For
instance, an application may already have a configuration file that uses
the '#' as the comment character.
The approach of using a new API with an extensible parameters structure was
used rather than simply adding a new argument to the existing API to allow
for additional arguments to be introduced in the future.

This commit adds the capability of parsing key=value pairs from such an

rte_cfgfile_load() API to enable this functionality. Any key=value pairs
found before the first section can be accessed in the section named
"GLOBAL".

Before this patch, the management of dependencies between directories
had several issues:
- the generation of .depdirs, done at configuration is slow: it can take
more than one minute on some slow targets (usually ~10s on a standard
PC without -j).
- for instance, it is possible to express a dependency like:
- app/foo depends on lib/librte_foo
- and lib/librte_foo depends on app/bar
But this won't work because the directories are traversed with a
depth-first algorithm, so we have to choose between doing 'app' before
or after 'lib'.
- the script depdirs-rule.sh is too complex.
- we cannot use "make -d" for debug, because the output of make is used for
the generation of .depdirs.
This patch moves the DEPDIRS-* variables in the upper Makefile, making
the dependencies much easier to calculate. A DEPDIRS variable is still
used to process library dependencies in LDLIBS.
After this commit, "make config" is almost immediate.
