Arnaldo Carvalho de MeloandNamhyung Kim 3de5a2bf5b perf python: Decrement the refcount of just created event on failure 
To avoid a leak if we have the python object but then something happens
and we need to return the operation, decrement the offset of the newly
created object.

Ian RogersandNamhyung Kim dc6d2bc2d8 perf sample: Make user_regs and intr_regs optional 
The struct dump_regs contains 512 bytes of cache_regs, meaning the two
values in perf_sample contribute 1088 bytes of its total 1384 bytes
size. Initializing this much memory has a cost reported by Tavian
Barnes <tavianator@tavianator.com> as about 2.5% when running `perf
script --itrace=i0`:
https://lore.kernel.org/lkml/d841b97b3ad2ca8bcab07e4293375fb7c32dfce7.1736618095.git.tavianator@tavianator.com/

Adrian Hunter <adrian.hunter@intel.com> replied that the zero
initialization was necessary and couldn't simply be removed.

This patch aims to strike a middle ground of still zeroing the
perf_sample, but removing 79% of its size by make user_regs and
intr_regs optional pointers to zalloc-ed memory. To support the
allocation accessors are created for user_regs and intr_regs. To
support correct cleanup perf_sample__init and perf_sample__exit
functions are created and added throughout the code base.

code is in util. To avoid needing to stub perf_kwork_add_work in
python.c, add a callback to struct perf_kwork and initialize it in
builtin-kwork to perf_kwork_add_work - this is the only struct
perf_kwork. This removes the need for the stub in python.c.

Ian RogersandArnaldo Carvalho de Melo 1ff2ca39b3 perf script: Move script_fetch_insn to trace-event-scripting.c 
Add native_arch as a parameter to script_fetch_insn rather than
relying on the builtin-script value that won't be initialized for the
dlfilter and python Context use cases. Assume both of those cases are
running natively.

Ian RogersandArnaldo Carvalho de Melo 04051b4a93 perf script: Move script_spec code to trace-event-scripting.c 
The script_spec code is referenced in util/trace-event-scripting but
the list was in builtin-script, accessed via a function that required
a stub function in python.c. Move all the logic to
trace-event-scripting, with lookup and foreach functions exposed for
builtin-script's benefit.

Ian RogersandArnaldo Carvalho de Melo 9557d1562a perf stat: Move stat_config into config.c 
stat_config is accessed by config.c via helper functions, but declared
in builtin-stat. Move to util/config.c so that stub functions aren't
needed in python.c which doesn't link against the builtin files.

To avoid name conflicts change builtin-script to use the same
stat_config as builtin-stat. Rename local variables in tests to avoid
shadow declaration warnings.

Ian RogersandArnaldo Carvalho de Melo d927e30ca0 perf script: Move find_scripts to browser/scripts.c

definition in builtin causes linking problems requiring a stub in

The util library code is used by the python module but doesn't have
access to the builtin files. Make a util/kvm-stat.c to match the
kvm-stat.h file that declares the functions and move the functions
there.
