Add rudimentary versioning to the dmevend protocol, allowing us to detect the
...
(protocol) version of the running dmeventd on the client side.
Right now this is only used in dmeventd -R.

Fix some compile warnings on RHEL5
...
- returned char not needed to be explicitly const
- warn if pipe() fails in clvmd (more fixes here needed for error paths...)
- assign (and ignore) read() output in drain buffer

Remove dead assignment of 'ret' value
...
Variable 'ret' assigned from _do_event() was actually not used and replaced with next
assignment without any read of the returned value.
Code is reformated - so the error path is put in the if() branch and normal
code is put after the 'if' together with FIXME comment.
FIXME lowprio: logging needs to be fixed in this code,
- multiple log_errors are printed, stacks are missing...

Fix clang warning for ntohl(*((uint32_t *)buf))
...
We cast (char*) to (uint32_t*) that changes alignment requierements.
For our case the code has been correct as alloca() returns properly
aligned buffer, however this patch make it cleaner and more readable
and avoids warning generation.

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).

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;
}
