util: Split out exec_dir from os_find_datadir
With this change, main() calls qemu_init_exec_dir and uses argv0 toinit exec_dir. The saved value can be retrieved withqemu_get_exec_dir later. It will be reused by module loading.

keep the PID file locked for the lifetime of the process
The lockf() call in qemu_create_pidfile() aims at ensuring mutualexclusion. We shouldn't close the pidfile on success (as introduced bycommit 1bbd1592), because that drops the lock as well [1]:
"File locks shall be released on first close by the locking process...
link the main loop and its dependencies into the tools

Introduce format string for pid_t
BeOS and Haiku on i386 use long for 32-bit types, including pid_t.Using %d with pid_t therefore results in a warning.
