The -I option (and hotkey) is reused for this. Skipping symbol resolution is
moved to the new -A option (and hotkey).

pmcstat: implement showing offsets into symbols in top mode

The -I option (and hotkey) is reused for this. Skipping symbol resolution is
moved to the new -A option (and hotkey).

While arguably this violates POLA I think it's a change for the better.
ALso note the -I option was added in head.

hwpmc: support sampling both kernel and user stacks when interrupted in kernel

This adds the -U options to pmcstat which will attribute in-kernel samples
back to the user stack that invoked the system call. It is not the default,
because when looking at kernel profiles it is generally more desirable to
merge all instances of a given system call together.

Although heavily revised, this change is directly derived from D7350 by
Jonathan T. Looney.

various: general adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

No functional change intended.

Extract a set of pmcstat functions and interfaces to the new internal
library -- libpmcstat.

This includes PMC logging module, symbols lookup functions,
ELF parsing, process management, PMC attachment, etc.

This allows to reuse code while building new hwpmc(4)-based applications.

Also add pmcstat_symbol_search_by_name() function that allows to find
mapped IP range for a given function name.
