Changed finds that use a string with a single character ("X"), to 'X'.
Remove using statements from header file.
Add a couple of missing includes.
Changed a couple of functions that take a string to const string& to
avoid extra copies.
Test: No warnings when compiled, unit tests pass.

* Wrote a relocatable ELF loader from scratch. The loader library loads
all objects in /system/etc/bpf/, parses and fixes up eBPF instructions
based on relocation information, creates maps and programs and pins
them. A single API call without arguments is made which results in this
operation. The API has all the information it needs from the filesystem
and the ELF objects, so there is no configuration stored in the code
calling the loader API essentially making it zero conf. Initially this
will be used by time_in_state statistics collection using tracepoints.
In the future, netd's eBPF C code should be rewritten to use this
infrastructure and the old ELF loader can be gotten rid off. This is the
first step.
* Link libbpf with libbpf_android which will come from the external/ bcc
project. This will be used for tracepoint and perf eBPF support. In the
future it can be used for other things as kernel eBPF support advances.
This patch will be merged only after bcc is cloned into external/ to
prevent build breakage.
