bug#54458: 27.2; erc-dcc-get: Re-entering top level after C stack overflow

[Fernando de Morais]

To reproduce, which is possible with 'emacs -Q' (when logged into an IRC
server and in a channel):

   /dcc get NICK FILE

   Results in:

   If FILE is larger than 120~150 MB, `erc-dcc' cannot handle the
download process. Transfers of such files causes "Re-entering top level
after C stack overflow" and, sometimes, crash.

   If I transfer multiple files (three or four), sometimes with sizes
smaller than those mentioned above, the C stack overflow hits way
earlier.

   If I reduce the `max-specpdl-size', the process stop and I don't get
the file properly.
