Improve ARM CPU info reporting.
This patch improves several things for Linux/ARM:
- Better detection of the number of CPUs on the target
device. The content of /proc/cpuinfo only matches the
number of "online" CPUs, which varies over time with
recent Android devices.
- Reconstruct the CPUID and ELF hwcaps values from
/proc/cpuinfo, this is useful to better identify
target devices in minidumps.
- Make minidump_dump display the new information
in useful ways.
- Write a small helper class to parse /proc/cpuinfo
and also use it for x86/64.
- Write a small helper class to parse sysfds cpu lists.
- Add a my_memchr() implementation.
- Add unit tests.
Tested on a Nexus S (1 CPU), Galaxy Nexus (2 CPUs)
and a Nexus 4 (4 CPUs).
