Use UUIDs instead of names while processing event handlers.
...
Internally, we used DM names instead of UUIDs while processing event
handlers. This caused problems while trying to vgrename a VG with active LVs
where the names are being changed and so the devices were not found then.
The patch also contains a little bit of refactoring, moving "build_dlid" code
found in dev_manager.c to "build_dm_uuid", now in lvm-string.c (so we have
build_dm_uuid and build_dm_name at one place).

As the const declaration of execvp is a bit weird, using local
dmeventdpath string.

Change exit() to _exit() in the child process. exit flushes stdio file buffers,
...
_exit doesn't. If there were some open files, an error in exec and subsequent
exit() would cause the buffers to be flushed twice.
Example:
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <sys/wait.h>
int main()
{
printf("buu");
if (!fork()) {
execl("/bin/true-not-exists", "/bin/true", NULL);
exit(1);
}
wait(NULL);
return 0;
}
