daaf575910 Build lib/ with WARNS=6 by default.
Similar to libexec/, do the same with lib/. Make WARNS=6 the norm and
lower it when needed.

I'm setting WARNS?=0 for secure/. It seems secure/ includes the
Makefile.inc provided by lib/. I'm not going to touch that directory.
Most of the code there is contributed anyway.

0ce207d2af Intel XScale hwpmc(4) support.
This brings hwpmc(4) support for 2nd and 3rd generation XScale cores.
Right now it's enabled by default to make sure we test this a bit.
When the time comes it can be disabled by default.
Tested on Gateworks boards.

A man page is coming.

791f5d5ba2 Not all Intel Core (TM) CPUs implement PMC_CLASS_IAF fixed-function
counters.  For such CPUs, use an alternate mapping of convenience
names to events supported by PMC_CLASS_IAP programmable counters.

597979c4b7 - Add support for nehalem/corei7 cpus. This supports all of the core
counters defined in the reference manual.  It does not support the
   'uncore' events.

0cfab8ddc1 - Add support for PMCs in Intel CPUs of Family 6, model 0xE (Core Solo
and Core Duo), models 0xF (Core2), model 0x17 (Core2Extreme) and
  model 0x1C (Atom).

  In these CPUs, the actual numbers, kinds and widths of PMCs present
  need to queried at run time.  Support for specific "architectural"
  events also needs to be queried at run time.

  Model 0xE CPUs support programmable PMCs, subsequent CPUs
  additionally support "fixed-function" counters.

- Use event names that are close to vendor documentation, taking in
  account that:
  - events with identical semantics on two or more CPUs in this family
    can have differing names in vendor documentation,
  - identical vendor event names may map to differing events across
    CPUs,
  - each type of CPU supports a different subset of measurable
    events.

  Fixed-function and programmable counters both use the same vendor
  names for events.  The use of a class name prefix ("iaf-" or
  "iap-" respectively) permits these to be distinguished.

- In libpmc, refactor pmc_name_of_event() into a public interface
  and an internal helper function, for use by log handling code.

- Minor code tweaks: staticize a global, freshen a few comments.

789140c0e7 - Sparsely number enumerations 'pmc_cputype' and 'pmc_event' in order to
reduce ABI disruptions when new cpu types and new PMC events are added
  in the future.
- Support alternate spellings for PMC events.  Derive the canonical
  spelling of an event name from its enumeration name in 'enum pmc_event'.
- Provide a way for users to disambiguate between identically named events
  supported by multiple classes of PMCs in a CPU.
- Change libpmc's machine-dependent event specifier parsing code to
  better support CPUs containing two or more classes of PMC resources.
