simpleperf: use libbacktrace_offline static library.
Device may not have libbacktrace_offline shared library, so always
using libbacktrace_offline static library.
Use simpleperf namespace to avoid conflicts with ThreadEntry in
libbacktrace.

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: fix some unknown symbols for report result.
Using debug shared libraries in /usr/lib/debug on linux host.
Match ip addresses with symbols by symbols' virtual addresses instead of
file offsets in elf file. Because symbols' file offsets in debug shared
libraries are different from those in original shared libraries.
Fix overlapped maps.

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.
