With the current API it is impossible to free the memory that was allocated
by stdin_task_register() after schedule() returns. This commit replaces the
APIs defined in stdin.h and stdout.h to remove the memory leaks which are
inevitable with the old API. We also make struct stdin_task and stdout_task
opaque because the API users (client.c, filter.c, recv.c and write.c) should
not be able to manipulate the fields of these structures directly.
The new stdout API differs from the new stdin API only in that stdout_new()
needs an additional argument to let the caller pass in a pointer to the
parent buffer tree node. Other than that, the APIs are symmetric.
Use the opportunity to do the non-blocking dance in std{in,out}_new()
and std{in,out}_free() rather than in the post-monitor functions. This
way we may get rid of the silly ->must_set_nonblock_flag boolean of struct
std{in,out}_task.

The GPLv2 line does not add any additional information, so drop
it. This leaves a single line of legalese text for most files, which
is about the amount of screen real estate it deserves.
This patch was created with the following script (plus some manual
fixups):
awk '{
if (NR <= 5) {
gs = gensub(/.*Copyright.* ([0-9]+).*Andre Noll.*/, "\\1", "g")
if (gs != $0)
year = gs
next
}
if (NR == 6 && year != "")
printf("/* Copyright (C) %s Andre Noll <maan@tuebingen.mpg.de>, see file COPYING. */\n", year)
print
}'

Done with
files=$(git grep -l 'Copyright (C) [0-9]\{4\}\(-2014\)* Andre Noll')
sed --in-place= -e 's/Copyright (C) \([0-9]\{4\}\)-2014 Andre Noll/Copyright (C) \1 Andre Noll/1' $files
In previous years we ran a similar script to set the second year in
the range to the current year. This is kind of silly, so let's get
rid of this useless information.
This commit replaces "Copyright (C) A-B" by "Copyright (C) A" in
all file headers, i.e. only the first year (A) is left in. Accurate
information including time stamps for each change can be obtained
from the git history.

The mail server on systemlinux.org was down for more than a week
lately, so let's use an alternative official address. This commit
changes all maan@systemlinux.org addresses to maan@tuebingen.mpg.de.
Most .c and .h files contain the email address in the copyright header,
so they must all be patched. Three other files contain the address
for a different reason:
* README lists email and git, gitweb and home page URLs
* configure.ac needs it for configure -h
* version.c contains it for the -V option of all commands

This renames stdin_set_defaults() to stdin_task_register() and changes
the function to register the stdin task. Before this patch, the task
was registered in the callers.

This year, we're really on time. The changes in this patch were
created by the following silly script:
files=$(git grep -l 'Copyright (C) [0-9]\{4\}\(-2013\)* Andre Noll')
sed --in-place= -e 's/Copyright (C) \([0-9]\{4\}\)-2013 Andre Noll/Copyright (C) \1-2014 Andre Noll/1' $files
sed --in-place= -e 's/Copyright (C) 2013 Andre Noll/Copyright (C) 2013-2014 Andre Noll/1' $files

The stdin/stdout code should restore the flags to the old value to
avoid surprises, for example in shell scripts.
This changes stdin.c and stdout.c to save the old value. It is
restored in ->post_select when the buffer tree node is removed and
no more I/O takes place.

Better late than never.

Hey, this is earlier than last year :)

para_client was the last user of the non-btr code in stdin.[ch]
and stdout.[ch]. Remove this unused code and update the documentation.

This introduces a memory leak to be fixed in a subsequent patch (the
buffer pool can not be freed in post_select() because there might
still be references to its area).

The bug in the wav filter which was fixed in the previous patch
could cause para_filter to hang because the stdin task would not
care whether the filter task has terminated.
Fix it by introducing an output_error pointer.

- Get rid of sched->select_ret. Tasks shouldn't care about the
return value of the select call.
- Kill task->private_data. Use container_of() instead.
- Remove task->event_handler. It is never necessary and only
makes the code more convoluted. The scheduler unregisters
tasks as soon as either the pre_select or the post_select
functions return an error.
- Rename task->ret to task->error and get rid of a couple
of error fields in other structs that usually only contained
a copy of the task's error value.
This conversion likely introduces many bugs that have to be
shaken out in subsequent patches. Hopefully it will result in
less error-prone code in the long run.

This way it's possible to tell at a later time why
the receiver/filter/writer terminated.
This allows to increase the delay for reconnecting in case
the receiver failed to connect to para_server: Let the receivers
set the error value to -E_RECV_EOF in case a normal end of file
event occurred and check this value when calculating the restart
barrier.

This makes the documentation complete again.

This was again straight forward.

The receiver/stdin_reader already have a corresponding field.
This patch also fixes a bug in the alsa_writer which was introduced
by the previous patch. This bug caused a playback delay of one second.
