Handle the SRCLINE_UNKNOWN case correctly when processing "srcfile".
Commiter note:
We can't just free it, as it was't allocated via malloc, its a guard

To remove direct access to libslang functions, with the immediate goal
of implementing horizontal scrolling at the ui_browser level, but also
because we may at some point want to implement ui_browser with other UIs
in addition to the current libslang implementation.

To remove direct access to libslang functions, with the immediate goal
of implementing horizontal scrolling at the ui_browser level, but also
because we may at some point want to implement ui_browser with other UIs
in addition to the current libslang implementation.

"perf probe --lines sys_poll" shows only the first line of sys_poll,
because the SYSCALL_DEFINE macro:
----
SYSCALL_DEFINE*(foo,...)
{
body;
}
----
is expanded as below (on debuginfo)
----
static inline int SYSC_foo(...)
{
body;
}
int SyS_foo(...) <- is an alias of sys_foo.
{
return SYSC_foo(...);
}
----
So, "perf probe --lines sys_foo" decodes SyS_foo function and it also skips
inlined functions(SYSC_foo) inside the target function because those functions
are usually defined somewhere else.
To fix this issue, this fix checks whether the inlined function is defined at
the same point of the target function, and if so, it doesn't skip the inline
function.

This patchkit adds the ability to set callgraph mode (fp, dwarf, lbr) per
event. This in term can reduce sampling overhead and the size of the
perf.data.
Here is an example.
perf record -e 'cpu/cpu-cycles,period=1000,call-graph=fp,time=1/,cpu/instructions,call-graph=lbr/' sleep 1
perf evlist -v
cpu/cpu-cycles,period=1000,call-graph=fp,time=1/: type: 4, size: 112,
config: 0x3c, { sample_period, sample_freq }: 1000, sample_type:
IP|TID|TIME|CALLCHAIN|PERIOD|IDENTIFIER, read_format: ID, disabled: 1,
inherit: 1, mmap: 1, comm: 1, enable_on_exec: 1, task: 1, sample_id_all:
1, exclude_guest: 1, mmap2: 1, comm_exec: 1
cpu/instructions,call-graph=lbr/: type: 4, size: 112, config: 0xc0, {
sample_period, sample_freq }: 4000, sample_type:
IP|TID|TIME|CALLCHAIN|PERIOD|BRANCH_STACK|IDENTIFIER, read_format: ID,
disabled: 1, inherit: 1, freq: 1, enable_on_exec: 1, sample_id_all: 1,

Introduce --show-ref-call-graph for perf report to print reference
callgraph for no callgraph event.
Here is an example.
perf report --show-ref-call-graph --stdio
# To display the perf.data header info, please use
--header/--header-only options.

+ When multiple events are sampled, it may not be needed to collect
+ callgraphs for all of them. The sample sites are usually nearby,
+ and it's enough to collect the callgraphs on a reference event.
+ So user can use "call-graph=no" event modifier to disable callgraph
+ for other events to reduce the overhead.
+ However, perf report cannot show callgraphs for the event which
+ disable the callgraph.
+ This option extends the perf report to show reference callgraphs,
