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.

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,

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'
