Bring the code closer to ELinks 0.13.GIT commit
71ccbe0f8d made on 2007-11-07.
Don't define a separate download_flags_T typedef though,
because Doxygen generates nicer links if the enum is used directly.
Doxygen isn't too good at documenting the parameters of a callback
within the documentation of a parameter that points to the callback.
A typedef provides a better place to document the parameters.
If the user chose File -> Save formatted document and typed the name
of an existing file, ELinks offered to resume downloading the file.
There are a few problems with that:
* save_formatted_finish does not actually support resuming. It would
instead overwrite the beginning of the file and not truncate it.
* When save_formatted calls create_download_file, cdf_hop->data
ends up pointing to struct document. If the user then chooses to
resume, lun_resume would read *(int *)cdf_hop->data, hoping to
get cmdw_hop.magic or codw_hop.magic. struct document does not
begin with any such magic value.
* Because ELinks already has the formatted document in memory,
resuming saves neither time nor I/O.
So don't show the "Resume download of the original file" button in
this situation.
Except if they have external handlers.
When ELinks receives an event from a terminal, move that terminal to
the beginning of the global "terminals" list, so that the terminals
are always sorted according to the time of the most recent use. Note,
this affects the numbering of bookmark folders in session snapshots.
Add get_default_terminal(), which returns the most recently used
terminal that is still open. Use that in various places that
previously used terminals.prev or terminals.next. Four functions
fetch the size of the terminal for User-Agent headers, and
get_default_terminal() is not really right, but neither was the
original code; add TODO comments in those functions.
When the user chooses "Background and Notify", associate the download
with the terminal where the dialog box is. So any later messages will
then appear in that terminal, if it is still open. However, don't
change the terminal if the download has an external handler.
When a download gets some data, don't immediately check the associated
terminal. Instead, wait for the download to end. Then, if the
terminal of the download has been closed, use get_default_terminal()
instead. If there is no default terminal either, just skip any
message boxes.
ELinks attempted to display a message box on file_download.term, but
it had already closed that terminal and freed the struct terminal. To
fix this, reset file_download.term pointers to NULL when the terminal
is about to be destroyed. Also, assert in download_data_store() that
file_download.term is either NULL or in the global "terminals" list.

(cherry picked from commit 6e2476ea4d)
Replace almost all uses of enum connection_state with struct
connection_status. This removes the assumption that errno values used
by the system are between 0 and 100000. The GNU Hurd uses values like
ENOENT = 0x40000002 and EMIG_SERVER_DIED = -308.
This commit is derived from my attachments 450 and 467 to bug 1013.
I am reverting all copiousoutput support because of bug 917.
This reverts commit f6115e65ec.
Conflicts:
src/session/download.h: type_query.cgi, and Doxygen comments.
CGI scripts are distinguishable from normal files. I hope that this
fixes the bug 991. This commit also reverts the previous revert.

(cherry picked from commit 7ceba1e461)
This reverts commit 7ceba1e461,
which is causing an assertion to fail if I open the same PDF
twice in a row, even if I cancel the dialog box when ELinks
first asks which program to run:
INTERNAL ERROR at /home/Kalle/src/elinks-0.12/src/session/download.c:980: assertion download && download->conn failed!
Forcing core dump! Man the Lifeboats! Women and children first!
But please DO NOT report this as a segfault!!! It is an internal error, not a
normal segfault, there is a huge difference in these for us the developers.
Also, noting the EXACT error you got above is crucial for hunting the problem
down. Thanks, and please get in touch with us.
Program received signal SIGSEGV, Segmentation fault.

There is a fix available but I don't trust it yet.
