[PATCH v2 0/5] logging enhancements

[Stephen Hemminger <stephen@networkplumber.org>]

This patch set improves the log-level option in EAL.
It adds symbolic names for log levels (error, info, debug, etc)
and shell style matching of log levels.
   --log-level='pmd.ixgbe.*:debug'

The original syntax (which is maintained for compatibility)
used numeric values, comma as separator and regular expression
to match log level.

It was often documented as:
   --log-level='pmd.ixgbe.*,8' ...
but this only worked by accident. The period was really
a regular expression match any character (not match a period);
and the asterisk in regular expression is match repeated value.

v2
  - make facility table constant
  - rebase to include support for dynamic log late binding
  - add patch to make saving log level a private API
  - update driver docs

  eal: make eal_log_level save private
  log: add ability to match dynamic log based on shell pattern
  doc: update guides for current preferrred log level syntax
