This avoids having to retain a pointer just to check item is still in
the queue with ring_item_is_linked(&item->link).

Remove the need to release the item inside send_item callbacks.
This looks like a partial rollback of previous patch but is
to make clear the intention of the change.
The lifetime of items could extend a bit further but there
are no cases this small lag should cause problems.

This is quite confusing and prone to errors.
Use RedPipeItem reference counting instead.
To compensate for the additional reference due to red_pipe_item_ref
in RedChannel sub class with empty hold_item have to add a
red_pipe_item_unref call in send_item.

There is some inconsistent naming of RedChannelClient methods. Some
include the word 'peer' (which normally seems to refer to RedsStream).
Remove the 'peer' terminology from those functions that are basically
RedChannelClient methods.

Following commit e8017dd366 here
are some more ifdef simplification.
For PIXEL_ID and PIXEL_DIST macros,
the ifndef LZ_PLT defines are special cases of the LZ_PLT
(#else) defines, when pix_per_byte is 1
Now do_match can accept pix_per_byte param for all different
definitions (implementations).

This is a public RedClient API that handles updating itself rather than
having the RedChannelClient poke around at the internal structure in
rec_channel_client_seamless_migration_done().
spice-server-replay is built with the same settings as tests.
Currently the tests links to a convenience spice-server library.
A convenience library is a static library build with object file
for a dynamic library.
This make all tests contain all spice-server library code and not
linking to the spice-server dynamic library (the .so).
It's not a problem for most tests however this make impossible for
spice-server-replay utility to be used with a dynamic spice-server
library (you have to recompile it including the library).
This is a pity as you could for instance compare your system
library behavior with the library you are developing.
Also if we decide to install in a future the utility for testing
we would have lot of code duplication.

With my compile switches (which are mostly derived from RedHat spec
file) I'm getting this warning:
stream-test.c: In function 'sock_fd_read':
stream-test.c:66:43: warning: dereferencing type-punned pointer will
break strict-aliasing rules [-Wstrict-aliasing]
*fd = *((int *) CMSG_DATA(cmsg));
^
memcpy could decrease performance but as this is a test it's not
an issue.

Make sure is possible to include any headers alone.

}
# add library to compile all headers alones
exec 3>> Makefile.am
echo "

for hdr in *.h; do

This is the continuation of Christophe patches using reference
counting for RedPipeItem.
Extend it's usage.
This for instance leads to the removal of release_item callback.

The items of these pipe items were allocated staticaly inside the
StreamAgent structure. All others RedPipeItem are allocated dynamically.
This could solve possible future maintenance as the life of these
item is more easier to understand.
It's more easier to understand why reference where incremented.
It also make the StreamAgent structure a bit smaller.
