Summary:
Instead of existing calls to ps from gnu_parallel, call a new wrapper that does ps, looks for unit test like processes, and uses pstack or gdb to print thread stack traces. Also, using `ps -wwf` instead of `ps -wf` ensures output is not cut off.
For security, CircleCI runs with security restrictions on ptrace (/proc/sys/kernel/yama/ptrace_scope = 1), and this change adds a work-around to `InstallStackTraceHandler()` (only used by testing tools) to allow any process from the same user to debug it. (I've also touched >100 files to ensure all the unit tests call this function.)

Summary:
Currently, blob file checksums are incorrectly dumped as raw bytes
in the `ldb manifest_dump` output (i.e. they are not printed as hex).
The patch fixes this and also updates some test cases to reflect that
the checksum value field in `BlobFileAddition` and `SharedBlobFileMetaData`
contains the raw checksum and not a hex string.

Test Plan:
`make check`
Tested using `ldb manifest_dump`
