augmented_raw_syscalls.c defines the bpf map 'syscalls' which is
initialized by perf tool in user space to indicate which system calls
are enabled for tracing, on the other flip eBPF program relies on the
map to filter out the trace events which are not enabled.
The map also includes a field 'string_args_len[6]' which presents the
string length if the corresponding argument is a string type.
Now the map 'syscalls' is not used, bpf program doesn't use it as filter
anymore, this is replaced by using the function bpf_tail_call() and
PROG_ARRAY syscalls map. And we don't need to explicitly set the string
length anymore, bpf_probe_read_str() is smart to copy the string and
return string length.
Therefore, it's safe to remove the bpf map 'syscalls'.
To consolidate the code, this patch removes the definition of map
'syscalls' from augmented_raw_syscalls.c and drops code for using
the map in the perf trace.
Note, since function trace__set_ev_qualifier_bpf_filter() is removed,
calling trace__init_syscall_bpf_progs() from it is also removed. We
don't need to worry it because trace__init_syscall_bpf_progs() is
still invoked from trace__init_syscalls_bpf_prog_array_maps() for
initialization the system call's bpf program callback.

On Arm64 a case is perf tools fails to find the corresponding trace
point folder for system calls listed in the table 'syscalltbl_arm64',
e.g. the generated system call table contains "lookup_dcookie" but we
cannot find out the matched trace point folder for it.
We need to figure out if there have any issue for the generated system
call table, on the other hand, we need to handle the case when trace
point folder is missed under sysfs, this patch sets the flag
syscall::nonexistent as true and returns the error from
trace__read_syscall_info().
Another problem is for trace__syscall_info(), it returns two different
values if a system call doesn't exist: at the first time calling
trace__syscall_info() it returns NULL when the system call doesn't exist,
later if call trace__syscall_info() again for the same missed system
call, it returns pointer of syscall. trace__syscall_info() checks the
condition 'syscalls.table[id].name == NULL', but the name will be
assigned in the first invoking even the system call is not found.
So checking system call's name in trace__syscall_info() is not the right
thing to do, this patch simply checks flag syscall::nonexistent to make
decision if a system call exists or not, finally trace__syscall_info()
returns the consistent result (NULL) if a system call doesn't existed.

Rather than controlling the list output with passed flags, add
callbacks that are called when an event or metric are
encountered. State is passed to the callback so that command line
options can be respected, alternatively the callbacks can be changed.
Fix a few bugs:
- wordwrap to columns metric descriptions and expressions;
- remove unnecessary whitespace after PMU event names;
- the metric filter is a glob but matched using strstr which will
always fail, switch to using a proper globmatch,
- the detail flag gives details for extra kernel PMU events like
branch-instructions.
In metricgroup.c switch from struct mep being a rbtree of metricgroups
containing a list of metrics, to the tree directly containing all the
metrics. In general the alias for a name is passed to the print
routine rather than being contained in the name with OR.
Committer notes:
Check the asprint() return to address this on fedora 36:

Fix ps.pmu_glob setting when dealing with *:* events, it was being left

SRS cap is the hardware cap telling if the hardware IOMMU can support
requests seeking supervisor privilege or not. SRE bit in scalable-mode
PASID table entry is treated as Reserved(0) for implementation not
supporting SRS cap.
Checking SRS cap before setting SRE bit can avoid the non-recoverable
fault of "Non-zero reserved field set in PASID Table Entry" caused by
setting SRE bit while there is no SRS cap support. The fault messages
look like below:
DMAR: DRHD: handling fault status reg 2
DMAR: [DMA Read NO_PASID] Request device [00:0d.0] fault addr 0x1154e1000
[fault reason 0x5a]

The A/D bits are preseted for IOVA over first level(FL) usage for both
kernel DMA (i.e, domain typs is IOMMU_DOMAIN_DMA) and user space DMA
usage (i.e., domain type is IOMMU_DOMAIN_UNMANAGED).
Presetting A bit in FL requires to preset the bit in every related paging
entries, including the non-leaf ones. Otherwise, hardware may treat this
as an error. For example, in a case of ECAP_REG.SMPWC==0, DMA faults might
occur with below DMAR fault messages (wrapped for line length) dumped.
