If a shorter string ends a longer string then the shorter string may
reuse the longer string at an offset. For example, on x86 the event
arith.cycles_div_busy and cycles_div_busy can be folded, even though
they have difference names the strings are identical after 6
characters. cycles_div_busy can reuse the arith.cycles_div_busy string
at an offset of 6.
In pmu-events.c this looks like the following where the 'also:' lists
folded strings:
/* offset=177541 */ "arith.cycles_div_busy\000\000pipeline\000Cycles the divider is busy\000\000\000event=0x14,period=2000000,umask=0x1\000\000\000\000\000\000\000\000\000" /* also: cycles_div_busy\000\000pipeline\000Cycles the divider is busy\000\000\000event=0x14,period=2000000,umask=0x1\000\000\000\000\000\000\000\000\000 */
As jevents.py combines multiple strings for an event into a larger
string, the amount of folding is minimal as all parts of the event must
align. Other organizations can benefit more from folding, but lose space
by say recording more offsets.

The pmu_events array requires 15 pointers per entry which in position
independent code need relocating. Change the array to be an array of
offsets within a big C string. Only the offset of the first variable is
required, subsequent variables are stored in order after the \0
terminator (requiring a byte per variable rather than 4 bytes per
offset).
The file size savings are:
no jevents - the same 19,788,464bytes
x86 jevents - ~16.7% file size saving 23,744,288bytes vs 28,502,632bytes
all jevents - ~19.5% file size saving 24,469,056bytes vs 30,379,920bytes
default build options plus NO_LIBBFD=1.
For example, the x86 build savings come from .rela.dyn and
.data.rel.ro becoming smaller by 3,157,032bytes and 3,042,016bytes
respectively. .rodata increases by 1,432,448bytes, giving an overall
4,766,600bytes saving.
To make metric strings more shareable, the topic is changed from say
'skx metrics' to just 'metrics'.
To try to help with the memory layout the pmu_events are ordered as used
by perf qsort comparator functions.

The current code assumes that a struct pmu_event can be iterated over
forward until a NULL pmu_event is encountered.
This makes it difficult to refactor pmu_event.
Add a loop function taking a callback function that's passed the struct
pmu_event.
This way the pmu_event is only needed for one element and not an entire
array.
Switch existing code iterating over the pmu_event arrays to use the new
loop function pmu_events_table_for_each_event.

Preparation for hiding pmu_events_map as an implementation detail. While
the map is passed, the table of events is all that is normally wanted.
While modifying the function's types, rename pmu_events_map__find to
pmu_events_table__find to match later encapsulation. Similarly rename
pmu_add_cpu_aliases_map to pmu_add_cpu_aliases_table.

Sort the JSON files entries on conversion to C. The sort order tries to
replicated cmp_sevent from pmu.c so that the input there is already
sorted except for sysfs events. Specifically, the sort order is given by
the tuple:
(not j.desc is None, fix_none(j.topic), fix_none(j.name), fix_none(j.pmu), fix_none(j.metric_name))
which is putting events with descriptions and topics before those
without, then sorting by name, then pmu and finally metric_name
Add the topic to JsonEvent on reading to simplify. Remove an unnecessary
lambda in the JSON reading.

When 'all' is passed as the architecture generate a mapping table for
all architectures. This simplifies testing. To identify the table for an
architecture add an arch variable to the pmu_events_map.

Sstc extension allows the guest to program the vstimecmp CSR directly
instead of making an SBI call to the hypervisor to program the next
event. The timer interrupt is also directly injected to the guest by
the hardware in this case. To maintain backward compatibility, the
hypervisors also update the vstimecmp in an SBI set_time call if
the hardware supports it. Thus, the older kernels in guest also
take advantage of the sstc extension.
