Previously, the decoder would indicate begin / end by a branch from / to
zero. That hides useful information, in particular when a trace ends
with a call. To prepare for remedying that, add Intel PT decoder flags
for trace begin / end and map them to the existing sample flags.

thread_stack__process() is used to create call paths for database
export. Improve the handling of trace begin / end to allow for a trace
that ends in a call.
Previously, the Intel PT decoder would indicate begin / end by a branch
from / to zero. That hides useful information, in particular when a
trace ends with a call. Before remedying that, enhance the thread stack
so that it identifies the trace end by the flag instead of by ip == 0.

thread_stack__event() is used to create call stacks, by keeping track of
calls and returns. Improve the handling of trace begin / end to allow
for a trace that ends in a call.
Previously, the Intel PT decoder would indicate begin / end by a branch
from / to zero. That hides useful information, in particular when a
trace ends with a call. Before remedying that, enhance the thread stack
so that it does not expect to see the 'return' for a 'call' that ends
the trace.
Committer notes:
Added this:
return thread_stack__push(thread->ts, ret_addr,
- flags && PERF_IP_FLAG_TRACE_END);
+ flags & PERF_IP_FLAG_TRACE_END);

Add branch types to cover different combinations with "trace begin" or
"trace end".
Previously, the Intel PT decoder would indicate begin / end by a branch
from / to zero. That hides useful information, in particular when a
trace ends with a call. Before remedying that, prepare the database
export to export branch types with more combinations that include trace
begin / end. In those cases extend the descriptions to include 'trace
begin' and 'trace end' separately.

When building in ClearLinux using 'make PYTHON=python3' with gcc 8.2.1
it fails with:

with the following error:

Stephane reported a possible issue in the ordered events code, which

When ordering events, we use preallocated buffers to store separate
events. Those buffers currently don't have their own struct, but since
they are basically an array of 'struct ordered_event' objects, we use
the first event to hold buffers data - list head, that holds all buffers
together:
struct ordered_events {
...
struct ordered_event *buffer;
...
};
struct ordered_event {
u64 timestamp;
u64 file_offset;
union perf_event *event;
struct list_head list;
};
This is quite convoluted and error prone as demonstrated by free-ing
issue discovered and fixed by Stephane in here [1].
This patch adds the 'struct ordered_events_buffer' object, that holds
the buffer data and frees it up properly.

Commit 1c5aae7710bb ("perf machine: Create maps for x86 PTI entry
trampolines") revealed a problem with maps__find_symbol_by_name() that
resulted in probes not being found e.g.
$ sudo perf probe xsk_mmap
xsk_mmap is out of .text, skip it.
Probe point 'xsk_mmap' not found.
Error: Failed to add events.
maps__find_symbol_by_name() can optionally return the map of the found
symbol. It can get the map wrong because, in fact, the symbol is found
on the map's dso, not allowing for the possibility that the dso has more
than one map. Fix by always checking the map contains the symbol.

use its 'initial_delay' member instead of the static one.
