223b5f757f docs: explain inconsistency of _{read,write}_all()
These functions are inconsistent with our normal conventions in that
they set an output variable to a specified value, even in the case that
an error is thrown.

Document very clearly that this should be considered exceptional.

76b890d0f1 Add g_input_stream_read_all_async()
Add an asynchronous version of _read_all().

This API is not fully consistent with the normal expectations of a
non-asynchronous version.  Consistency between the sync and async version is
probably more important.

The API will still bind correctly, but access to all functionality will
not be available: specifically, in the case of an error, higher level
languages will be unable to determine how many bytes were successfully
read before the error.  Most users will probably not want to use this
information anyway, so this is OK -- and if they do need the
information, then they can just write the loop for themselves.

Heavily based on a patch from Ignacio Casal Quinteiro.

48c7d041e2 doc: improve doc of g_input_stream_read()
I recently needed to nul-terminate the returned buffer, and I wasn't
sure if g_input_stream_read() does that or not. I've checked
glocalfileinputstream.c, which calls read(2) which doesn't nul-terminate
the buffer. So I assume it's the same behavior for all GInputStream
subclasses.

94a232a4ed GInputStream: Add g_input_stream_async_read_is_via_threads()
In implementing a better g_output_stream_splice_async() and possibly
other situtations it's helpful to know whether the input stream's
read function internally uses threads. If it and the output stream's
write async functions use threads, then the splice function could
spawn a single thread for better efficiency.

This patch adds a function to determine whether an input stream's
g_input_stream_read_async() function internally uses threads.

54cc43630d Rename the generated private data getter function
As it turns out, we have examples of internal functions called
type_name_get_private() in the wild (especially among older libraries),
so we need to use a name for the per-instance private data getter
function that hopefully won't conflict with anything.

acfa6e2337 gio: callback_data is the task not the task data.
skip_callback_wrapper expect the user_data (callback_data)
to be the task holding the task_data, not the task_data
itself.
Otherwise the task_data is cast as GTask and then task_data
is extracted from this bogus task.

1738d5f1ef GInputStream: fix default g_input_stream_skip_async() logic
g_input_stream_real_skip_async() wants to use read_async() normally,
but will use skip() in a thread instead if it sees that read_async()
will end up using threads. Except that the test for "will read_async()
use threads" never got updated to know about the GPollableInputStream
support in read_async(), so it was doing the wrong thing in that case.
Fix.

Also remove a small bit of pre-GTask cruft noticed nearby.

82d914d808 gio: add g_async_result_is_tagged()
Rather than doing a two step first-check-the-GAsyncResult-subtype-then-
check-the-tag, add a GAsyncResult-level method so that you can do them
both at once, simplifying the code for "short-circuit" async return
values where the vmethod never gets called.

f8532a13e2 gio: Add g_async_result_legacy_propagate_error()
Finish deprecating the "handle GSimpleAsyncResult errors in the
wrapper function" idiom (and protect against future GSimpleAsyncResult
deprecation warnings) by adding a "legacy" GAsyncResult method
to do it in those classes/methods where it had been traditionally
done.

(This applies only to wrapper methods; in cases where an _async
vmethod explicitly uses GSimpleAsyncResult, its corresponding _finish
vmethod still uses g_simple_async_result_propagate_error.)

538b2f106d gio: handle GSimpleAsyncResult errors in _finish vmethods
Originally, the standard idiom with GSimpleAsyncResult was to handle
all errors in the _finish wrapper function, so that vmethods only had
to deal with successful results. But this means that chaining up to a
parent _finish vmethod won't work correctly. Fix this by also checking
for errors in all the relevant vmethods. (We have to redundantly check
in both the vmethod and the wrapper to preserve compatibility.)

800d6ff111 gio: add GBytes-based input/output stream methods
Using a caller-supplied buffer for g_input_stream_read() doesn't
translate well to the semantics of many other languages, and using a
non-refcounted buffer for read_async() and write_async() makes it
impossible to manage the memory correctly currently in
garbage-collected languages.

Fix both of these issues by adding a new set of methods that work with
GBytes objects rather than plain buffers.

fd3ec4df87 Fix several recently-introduced bugs in g_output_stream_write_async()
g_output_stream_write_async() was not initializing the newly-added
members of the WriteData structure, causing various problems.

Also, g_input_stream_read_async() was now leaking its cancellable. Fix
that as well.

00ee06e6a3 gio: use GPollable* to implement fallback read_async/write_async
If a GInputStream does not provide a read_async() implementation, but
does implement GPollableInputStream, then instead of doing
read-synchronously-in-a-thread, just use
g_pollable_input_stream_read_nonblocking() and
g_pollable_input_stream_create_source() to implement an async read in
the same thread. Similarly for GOutputStream.

Remove a bunch of existing read_async()/write_async() implementations
that are basically equivalent to the new fallback method.

f2c77ee718 g_input_stream_read[_finish]: document returning 0 on EOF
g_input_stream_read() does state that it returns 0 on end of file, but
not in the Returns: line, so it's easy to miss on a quick skim-read.

g_input_stream_read_async() documents that g_input_stream_read_finish()
returns 0 on end of file, but g_input_stream_read_finish() itself does
not.
