4f512a1919 ip_frag: fix double free of chained mbufs
The first mbuf and the last mbuf to be visited in the preceding loop
are not set to NULL in the fragmentation table.  This creates the
possibility of a double free when the fragmentation table is later freed
with rte_ip_frag_table_destroy().

5b9656b157 lib: build with meson
Add non-EAL libraries to DPDK build. The compat lib is a special case,
along with the previously-added EAL, but all other libs can be build using
the same set of commands, where the individual meson.build files only need
to specify their dependencies, source files, header files and ABI versions.

0d440d081c lib: fix missing includes in exported headers
Many exported headers rely on definitions found in rte_config.h without
including it, as shown by the following command:

 grep -L '^#include <rte_config.h>' -- \
  $(grep -Rl \
    $(sed -n '/^#define \([^ ]\+\).*$/{s//\1/;H;};${x;s/\n//;s/\n/\\|/g;p;}' \
      build/include/rte_config.h) \
    -- build/include/)

We cannot assume external applications will include rte_config.h on their
own, neither directly nor through a -include parameter like DPDK does
internally.

This not only causes obvious compilation failures that can be reproduced
with check-includes.sh such as:

 [...]/rte_memory.h:88:43: error: ‘RTE_CACHE_LINE_SIZE’ was not declared in
     this scope
  #define __rte_cache_aligned __rte_aligned(RTE_CACHE_LINE_SIZE)
                                            ^

It also results in less visible issues, for instance rte_hash_crc.h relying
on RTE_ARCH_X86_64's presence to provide dedicated inline functions.

This patch partially reverts the commit below and adds missing include
lines to the remaining files.

45a5f79886 ip_frag: rename map file to standardized name
The filenames of the linker map files for DPDK libraries, all follow a
standard format: rte_<libname>_version.map. The ip_frag version, however,

8d4d3a4f73 ip_frag: handle MTU sizes not aligned to 8 bytes
The rte_ipv4_fragment_packet API expects that the link/interface MTU value
passed in be divisible by 8 bytes.  Given the name of the parameter is
"mtu" rather than "frag_size" it is not necessarily the case that it will
be divisible by 8.  An MTU of 1500 happens to produce a max fragment size
of 1480 (1500 - sizeof(ipv4_hdr)) which is divisible by 8 but other MTU
values such as 1600 or 9000 do not produce values that are divisible by 8.

Unfortunately, the API checks that the frag_size value produced is
divisible by 8 with a call to RTE_ASSERT which is only enabled when the
RTE_LOG_LEVEL >= RTE_LOG_DEBUG.  In cases where the log level is set
normally the code silently continues and produces IP fragments that have
invalid fragment offset values.

An application may not have control over what MTU a user selects and rather
than have each application adjust the MTU to pass a suitable value to the
fragmentation API this change modifies the fragmentation API to handle
cases where the "mtu" argument is not divisible by 8 and automatically
adjust the internal "frag_size".

feb9f680cd mk: optimize directory dependencies
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.

50705e8e3c eal: add assert macro for debug
The macro RTE_VERIFY always checks a condition.
It is optimized with "unlikely" hint.
While this macro is well suited for test applications, it is preferred
in libraries and examples to enable such check in debug mode.
That's why the macro RTE_ASSERT is introduced to call RTE_VERIFY only
if built with debug logs enabled.

A lot of assert macros were duplicated and enabled with a specific flag.
Removing these #ifdef allows to test these code branches more easily
and avoid dead code pitfalls.

The ENA_ASSERT is kept (in debug mode only) because it has more
parameters to log.

7869536f3f mbuf: flatten struct vlan_macip
The vlan_macip structure combined a vlan tag id with l2 and l3 headers
lengths for tracking offloads. However, this structure was only used as
a unit by the e1000 and ixgbe drivers, not generally.

This patch removes the structure from the mbuf header and places the
fields into the mbuf structure directly at the required point, without
any net effect on the structure layout. This allows us to treat the vlan
tags and header length fields as separate for future mbuf changes. The
drivers which were written to use the combined structure still do so,
using a driver-local definition of it.

Reduce perf regression caused by splitting vlan_macip field. This is
done by providing a single uint16_t value to allow writing/clearing
the l2 and l3 lengths together. There is still a small perf hit to the
slow path TX due to the reads from vlan_tci and l2/l3 lengths being
separated. (<5% in my tests with testpmd with no extra params).
Unfortunately, this cannot be eliminated, without restoring the vlan
tags and l2/l3 lengths as a combined 32-bit field. This would prevent
us from ever looking to move those fields about and is an artificial tie
that applies only for performance in igb and ixgbe drivers. Therefore,
this patch keeps the vlan_tci field separate from the lengths as the
best solution going forward.

ea672a8b16 mbuf: remove the rte_pktmbuf structure
The rte_pktmbuf structure was initially included in the rte_mbuf
structure. This was needed when there was 2 types of mbuf (ctrl and
packet). As the control mbuf has been removed, we can merge the
rte_pktmbuf into the rte_mbuf structure.

Advantages of doing this:
  - the access to mbuf fields is easier (ex: m->data instead of m->pkt.data)
  - make the structure more consistent: for instance, there was no reason
    to have the ol_flags field in rte_mbuf
  - it will allow a deeper reorganization of the rte_mbuf structure in the
    next commits, allowing to gain several bytes in it

2505824261 ip_frag: fix order of key compare arguments
When using key compare function, it uses key length of the first
argument to determine how long should be the keys that are compared.
However, currently we are passing a key from the fragmentation table as
first argument. the problem with this is that this key is potentially
uninitialized (i.e. contains all zeroes, including key length). this
leads to a nasty bug of comparing only the key id's and not keys
themselves.

Of course, a safer way would be to do RTE_MAX between key lengths, but
since this compare is done per-packet, every cycle counts, so we just
use the key whose length is guaranteed to be correct because it comes
from an actual packet.
