This was too difficult for some static analyzers (CID 62876). In
addition, the pac_info_len assignment should really have explicitly
validated that there is room for the two octet length field instead of
trusting the following validation step to handle both this and the
actual pac_info_len bounds checking.

Even if the PAC file does not start with the proper header line, allow
the file to be used if it is empty. [Bug 423]

One of the pointers to the PAC buffer was not updated after realloc
and if the realloc ended up returning new pointer, the *pos pointer
was still pointing at the old location (i.e., freed memory at
this point).
