perf tests api-io: Use zfree() to reduce chances of use after free
...
Do defensive programming by using zfree() to initialize freed pointers
to NULL, so that eventual use after free result in a NULL pointer deref
instead of more subtle behaviour.

perf test: Move each test suite struct to its test
...
Rather than export test functions, export the test struct. Rename with a
suite__ prefix to avoid name collisions.
Committer notes:
Its '&suite__vectors_page', not '&suite__vectors_pages', noticed when
cross building to arm (32-bit).

tools api: Add a lightweight buffered reading api
...
The synthesize benchmark shows the majority of execution time going to
fgets and sscanf, necessary to parse /proc/pid/maps. Add a new buffered
reading library that will be used to replace these calls in a follow-up
CL. Add tests for the library to perf test.
Committer tests:
$ perf test api
63: Test api io : Ok
