timer: override CPU TSC frequency with OS value

The CPU provided value is often not accurate, allow overriding it
based on info from the host OS.

On Linux x86, if the tsc_known_freq cpu flag is missing, it means
the kernel doesn't trust it and calculates its own. We should do
the same to avoid drift.

On Freebsd, we have access to the kernel tsc_hz value, just use it.

timer: improve TSC estimation accuracy

In practice, the frequency is often not a nice round number, while
the estimation results are rather accurate, just a couple of KHz
away from the kernel's tsc_khz value, so it should suffice.

Rounding to 10MHz can cause a significant drift from real time,
up to a second per 10 minutes.

lib: add more logging helpers

Add helpers for logging messages in libraries instead of calling
RTE_LOG() directly.
Those helpers take care of adding a \n: this will make the transition to
RTE_LOG_LINE trivial.

Note:
- for acl and sched libraries that still has some debug multilines
messages, a direct call to RTE_LOG is used: this will make it easier to
notice such special cases,

set namespace prefix to threads

When looking at threads in a system, it can be confusing
to find some unknown threads without a clue it is started by DPDK.

Let's start all thread names with "dpdk-"
plus the driver name if it comes from a driver.

One more constraint: the thread names are generally limited
to 16 characters, including the NUL character.

lib: remove librte_ prefix from directory names

There is no reason for the DPDK libraries to all have 'librte_' prefix on
the directory names. This prefix makes the directory names longer and also
makes it awkward to add features referring to individual libraries in the
build - should the lib names be specified with or without the prefix.
Therefore, we can just remove the library prefix and use the library's
unique name as the directory name, i.e. 'eal' rather than 'librte_eal'
