For string values returned from telemetry, escape any values that cannot
normally appear in a json string. According to the json spec[1], the
characters than need to be handled are control chars (char value < 0x20)
and '"' and '\' characters.
To handle this, we replace the snprintf call with a separate string
copying and encapsulation routine which checks each character as it
copies it to the final array.

__rte_raw_cksum() (used by rte_raw_cksum() among others) accessed its
data through an uint16_t pointer, which allowed the compiler to assume
the data was 16-bit aligned. This in turn would, with certain
architectures and compiler flag combinations, result in code with SIMD
load or store instructions with restrictions on data alignment.
This patch keeps the old algorithm, but data is read using memcpy()
instead of direct pointer access, forcing the compiler to always
generate code that handles unaligned input. The __may_alias__ GCC
attribute is no longer needed.
The data on which the Internet checksum functions operates are almost
always 16-bit aligned, but there are exceptions. In particular, the
PDCP protocol header may (literally) have an odd size.
Performance impact seems to range from none to a very slight
regression.

A mempool consumes 3 memzones (with the default ring mempool driver).
The default DPDK configuration allows RTE_MAX_MEMZONE (2560) memzones.
Assuming there is no other memzones that means that we can have a
maximum of 853 mempools.
In the vhost library, the IOTLB cache code so far was requesting a
mempool per vq, which means that at the maximum, the vhost library
could request mempools for 426 qps.
This limit was recently reached on big systems with a lot of virtio
ports (and multiqueue in use).
While the limit on mempool count could be something we fix at the DPDK
project level, there is no reason to use mempools for the IOTLB cache:
- the IOTLB cache entries do not need to be DMA-able and are only used
by the current process (in multiprocess context),
- getting/putting objects from/in the mempool is always associated with
some other locks, so some level of lock contention is already present,
We can convert to a malloc'd pool with objects put in a free list
protected by a spinlock.

However, some parts of the code were missed, and some later code changes
broke this new convention (fixes were sent previous to this patch).
Change the VHOST_LOG_CONFIG/DATA helpers and always ask for a string
used as context. This should help limit regressions on this topic.
Most of the time, the context is the vhost-user device socket path.
For the rest when a vhost-user device can not be related, generic
names were chosen:
- "dma", for vhost-user async DMA operations,
- "device", for vhost-user device creation and lookup,
- "thread", for threads management,

In the virtio blk vDPA live migration use case, before the live
migration process, QEMU will set call fd to vDPA back-end. QEMU
and vDPA back-end stand by until live migration starts.
During live migration process, QEMU sets kick fd and a new call
fd. However, after the kick fd is set to the vDPA back-end, the
vDPA back-end configures device and data path starts. The new
call fd will cause some kind of "re-configuration", this kind
of "re-configuration" cause IO drop.
After this patch, vDPA back-end configures device after kick fd
and call fd are well set and make sure no IO drops.
This patch only impact virtio blk vDPA device and does not impact
net device.

Add support for using hugepages for worker lcore stack memory. The
intent is to improve performance by reducing stack memory related TLB
misses and also by using memory local to the NUMA node of each lcore.
EAL option '--huge-worker-stack[=stack-size-in-kbytes]' is added to allow
the feature to be enabled at runtime. If the size is not specified,
the system pthread stack size will be used.
