[PATCH 1/2] auparse: Remove quotes from parsed fields

[Marcelo Cerri <mhcerri@linux.vnet.ibm.com>]

Auparse just removes single quotes at the end of a field value and leaves
quotes at the beginning. With this patch, auparse removes quotes at the
beggining of a parsed field value and handles double quotes at the same way as
single quotes.

This is a simple test program to reproduce the problem:

-----
int main() {
	const char *buffer= "type=VIRT_RESOURCE msg=audit(1327574186.046:174): user pid=6748 uid=0 auid=500 ses=1 subj=unconfined_u:unconfined_r:unconfined_t:s0 msg='virt=kvm resrc=net reason=start vm=\"CentOS\" uuid=fb4149f5-9ff6-4095-f6d3-a1d03936fdfa old-net='?' new-net='52:54:00:DB:AE:B4 test': exe=\"/usr/sbin/libvirtd\" hostname=? addr=? terminal=? res=success'\n";
	auparse_state_t *au = auparse_init(AUSOURCE_BUFFER, buffer);
	if (au == NULL) return -1;
	while (auparse_next_event(au) > 0) {
		printf("%s\n", auparse_find_field(au, "new-net"));
	}
	auparse_destroy(au);
	return 0;
}
