2c6a14dd56 Delete all socket files on servald start
If serval does not close properly, socket files are kept in
/data/data/org.servalproject/var/serval-node. Therefore, we need to clean up
when servald starts.

b7185a294f Fix keyring SEGV bug
Sometimes, when adding a PIN to a keyring (eg, when opening a keyring
file), a SEGV would be caused while trying to validate the MAC for an
entry which apparently had zero keypair entries.

Changed some keyring struct 'int' fields to 'unsigned int', to ensure
that comparison logic behaves as expected.

Refactored some keyring code for more clarity and code maintenance
safety.

Added TODO comment about keyring file format non-back-compatibility.

705f414a4d Fix SEGV bug in keyring_enter_pin()

390655580d Add 'rhizome delete' and 'rhizome clean' commands
sqlite_void_exec() and its ilk now return the count of changed rows, not
just zero, on success

sqlite_exec_prepared() and its ilk now return the count of rows (number
of step results SQLITE_ROW), instead of just zero, on success

rhizome_clean() function now produces an optional report of its changes

rhizome_fail_write() and rhizome_finish_write() now log WARNings not
ERRORs if the SQL DELETE FROM FILES or DELETE FROM FILEBLOBS statements
fail

Refactor rhizome_open_read() to use sqlite_exec_int64()

Ensure that 'rhizome extract' and 'rhizome dump' commands return exit
status of 1 in "not found" conditions, not 255, which is reserved for
errors

Test cases for four new commands: 'rhizome delete bundle', 'rhizome
delete manifest', 'rhizome delete payload' and 'rhizome delete file'
(no test case for 'rhizome clean' yet)

d3c2205d44 Add os.c and "os.h", replacing mkdirs.c
The new header "os.h" defines a supplemental API around existing basic
operating system services (system calls and standard library functions).

This allows non-servald executables to take advantage of this API without
having to include serval.h and bringing in all the other servald link-time
baggage.
