With this change, main() calls qemu_init_exec_dir and uses argv[0] to
init exec_dir. The saved value can be retrieved with
qemu_get_exec_dir later. It will be reused by module loading.

Using the main loop code from QEMU enables tools to operate fully
asynchronously.  Advantages include better Windows portability (for some
definition of portability) over glib's.

string is allocated by g_malloc, will not be used after putenv, should be
free before return.

Paolo Bonzini <pbonzini@redhat.com> confirmed this is safe under Wine:

"1) the underlying Win32 APIs require separate arguments for the
variable and value; 2) even though in the end Wine stores the
environment as name=value
(http://source.winehq.org/source/dlls/ntdll/env.c), it does so in a
single consecutive block of memory, not as a char* array like POSIX
does.  While (2) might apply only to Wine, (1) surely applies to Windows
as well."

The function that writes pidfile for win32 uses WriteFileEx which is an
asynchronous IO function. The arguments given to WriteFileEx are allocated on
the stack and one of them is "in out". When the IO operation is actually
executed the calling function has already returned, so the arguments are no
longer allocated or allocated to another frame.

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

Unfortunately POSIX:2008 does not define a PRId* string for pid_t.

In some places pid_t was previously casted to long and %ld hardcoded.
The predecessor of this patch added another upcast for the simpletrace
filename but was not applied to date.

Since new uses of pid_t with %d keep creeping in, let's instead define
an OS-dependent format string and use that consistently.

Win32 does not support line-buffering, but it allows
unbuffered output.

Unbuffered output is a good approximation. For typical output
statements which usually end with '\n', it's even identical.

Buffered output is unusable for program traces because of
its large delay.
