app: use portable variadic macros

Many places are using a GCC extension related to variadic macros,
where a name prepends the ellipsis. This results in a warning like
the one below when compiling the code with MSVC:

app\test-pmd\testpmd.h(1314): error C2608:
invalid token '...' in macro parameter list

Variadic macros became a standard part of the C language with C99.
GCC, Clang and MSVC handle them properly.

The fix is to remove the prefix name (args... becomes ...) and use
__VA_ARGS__.

net: add IPv4 cksum function for simple cases

There are multiple instances in the DPDK app folder where we set up an
IP header and then compute the checksum field by direct addition of
nine uint16_t values in the header (20 bytes less the cksum field).
The existing rte_ip.h checksum function is more general than necessary
here and requires that the checksum field is already set to zero -
rather than having it skipped.

Fix the code duplication present in the apps by creating a new
rte_ipv4_cksum_simple function - taking the code from the existing
testpmd icmpecho.c file - and using that in app/test, testpmd and
testeventdev.

Within that new function, we can adjust slightly how the typecasting to
uint16_t is done, and thereby ensure that the app can all be compiled
without -Wno-address-of-packed-member compiler flag.

app/eventdev: measure DMA adapter latency

Move DMA ops to use mempool to prevent using the
same ops before completion.
This also allows us to measure forward latency.

app/eventdev: increase default queue depth for cryptodev

With crypto adapter, larger queue depths are desirable since same queue
could be used from multiple cores at the same time. With devices that
are capable of doing large bursts, larger queues would help in multi
core management of same queue.

Increase default queue depth in cryptodev to cater to such use cases.
