rillig | sbin, usr.bin, usr.sbin: remove redundant getopt declarations
No binary change, except for assertion line numbers in tprof.

ryo | Improve tprof(4)
- Multiple events can now be handled simultaneously.
- Counters should be configured with TPROF_IOC_CONFIGURE_EVENT in advance,
instead of being configured at TPROF_IOC_START.
- The configured counters can be started and stopped repeatedly by
PROF_IOC_START/TPROF_IOC_STOP.
- The value of the performance counter can be obtained at any timing as a 64bit
value with TPROF_IOC_GETCOUNTS.
- Backend common parts are handled in tprof.c as much as possible, and functions
on the tprof_backend side have been reimplemented to be more primitive.
- The reset value of counter overflows for profiling can now be adjusted.
It is calculated by default from the CPU clock (speed of cycle counter) and
TPROF_HZ, but for some events the value may be too large to be sufficient for
profiling. The event counter can be specified as a ratio to the default or as
an absolute value when configuring the event counter.
- Due to overall changes, API and ABI have been changed. TPROF_VERSION and
TPROF_BACKEND_VERSION were updated.

skrll | Output alignement - give lwp 6 characters

jmcneill | Print the path that we failed to open on error

maxv | branches: 1.3.2; 1.3.4; 1.3.6;
Finish the Skylake/Kabylake table, and improve the output of "tprof analyze".
|
| 1.2 |
| 13-Jul-2018 |
maxv | Ask for a file path with the "analyze" command, instead of reading stdin.
|
| 1.1 |
| 13-Jul-2018 |
maxv | Merge tpfmt(1) into tprof(8). We want to have access to everything with
only one tool. The code is copied mostly as-is, and the functionality is
available via the "analyze" command.
Eg:
tprof monitor -e llc-misses:k -o myfile.out sleep 20
tprof analyze < myfile.out
Will move soon, I don't like the reading via stdin.
