simpleperf: enable two options by default.
Enable dumping symbols in record cmd by default,
and change --dump-symbols option into --no-dump-symbols option.
Show brief call graph in report cmd by default,
and change --brief-callgraph option into --full-callgraph option.
Make the change because these two behaviors are always recommended.
Bug: None.

simpleperf: fix unknown binary in samples.
1. Wrong ip addresses in callchain can map to unknown binary. They
should be omitted.
2. When unknown binary is really hitted in samples, which is unlikely
to happen, make sure report-sample cmd will not skip the file id of
unknown binary.
3. Add corresponding test.

simpleperf: build libsimpleperf_inplace_sampler library.
libsimpleperf_inplace_sampler.so is a library linked with
user's app. It opens a unix socket server and waits for
simpleperf's profiling request. This patch doesn't contain
code generating real samples, instead it uses a fake sample
for testing.
Add runtest for 32bit. Increase runtest duration to 2 seconds
and adjust some args in runtest.conf to make test result stable.
Fix one tiny error in cmd_report.cpp to report correctly
in `report --sort comm,symbol`.

simpleperf: Improve Callgraph.
1. Reduce columns used by callgraph by reducing spaces between
entries from 11 to 4. This helps to show more entries in the limited screen width.
2. Add [hit-in-function] line for each entry, so we know the percentage
of samples hit in the function and samples hit in the children functions.
3. Add --kallsyms option for report command.
After all, The callgraph is changed like below.
Before change:

Callgraph in caller mode shows how functions call others, i.e.,

mode. So change to default option to use caller mode.

When running unit tests on arm64 devices:

ERROR: can't unwind data recorded on a different architecture.
It is because ReportCommandtest.dwarf_callgraph opens a perf.data
recorded on x86_64, and changes current_arch. It causes a problem when
the test record_cmd.dwarf_callchain_sampling calls libbacktrace built
on aarch64. Athough it doesn't make the test fail, we should fix this.

Simpleperf: Don't load whole perf.data into memory.
perf.data can be too large to be loaded into memory.
To avoid this, use fread() instead of mmap() to read perf.data,
and always use RecordCache to sort records.
Fix unit tests failure caused by previous change.

Simpleperf: use OneTimeFreeAllocator to allocate symbol names.
simpleperf report takes a lot of time mallocing and freeing memory.
This change reduces the time to free memory.
Before this change:
$sudo simpleperf stat simpleperf report
Performance counter statistics:
3,258,481,203 cpu-cycles # 2.290946 GHz (80%)
4,147,660,154 instructions # 0.785619 cycles per instruction (79%)
Total test time: 1.422330 seconds.
After this change:
$sudo simpleperf stat simpleperf report
Performance counter statistics:

Simpleperf: refactor dso.
Having DsoEntry and DsoFactory confuses me which part code should belong to.
This change merges the two into class Dso and makes things clear.
It is also a preparation for performance optimization in Dso.

Simpleperf: fix the process of parsing records.
It is not correct to parse all the mmap records first, then parse
all the sample records. Instead, records should be parsed one by one.
This change also fix the bug of not writing kernel build id in
record command, which is introduced previously.
