b2caacbf68 Avoid unnecessary recursion in ensuredir() 
Before we made the ensuredir() function recurse on itself
if we couldn't open /run/rdo, after mkdir()'ing it,
to retry opening the directory.

Now we simplify and add a simple fd = open([...]) directly
after the mkdir(), to avoid the recursion.
If the second open fails, we error out.

4ed6a6d75a Fix memory leak in getconf() 
As getline() calls malloc() to allocate new memory
for our usage, we have to free() it after.

c80be89ef9 Remove debug printf & use strlen() at write 
In sessions.h, now line 95, we used sizeof(ts_str) to
determine how much to write, but as ts_str can be longer
than the actual string written, it wrote random data
after the actual timestamp.

24638bc999 Add sessions feature 
This is by far the heaviest feature of rdo, justifying
its own file for its 140loc.

It creates sessions, inspired by the way doas does it.
We use the /run/rdo temporary folder to store files in the
format of /run/rdo/pid-ts, pid being the PID of the process
that executed rdo, and ts being the timestamp at which said
process started.

As no 2 processes can have the exact same PID and startup time
(startup time is measured in the milliseconds), this seems secure.

Closes #4.
