After the previous commit, spice_bitmap_try_as_pixman() can be
simplified as its #ifdef WORDS_BIGENDIAN exactly match what the
PIXMAN_LE_ constants do.
When using image compression on PowerPC architecture, colors are in
wrong order ARGB -> BGRA.
This commit introduces macros, that will change the color order
according to machine endianness.
Theese macros are similar to QEMU macros in qemu-pixman.h
This allows libtool/automake to correctly add a dependency from
libspice-common.la to test_marshallers. With _LDFLAGS, the binary won't
automatically get rebuilt/relinked when the lib changes.
libcacard.h requires 2.5.1. Keep compatibility for older versions until
the transition in distros to the standalone version is done.

This makes it possible to warn the developer that the GStreamer elements
needed at runtime are missing and give him a hint on how to fix the
issue.

A call to SPICE_WARNING() anywhere in the configure file results in the
warning being printed at the end of the configure run where it will be
be visible. This makes it possible to keep the SPICE_WARNING() calls
together with the related feature checks instead of having to put a
separate AC_MSG_WARN() call near the end.

SPICE_CHECK_SMARTCARD documentation ends with a '-------' comment, but
the # to start the comment is missing, causing a warning message when
running configure.
GInetAddress is defined in gio, not glib. Not checking for gio-2.0 in
SPICE_CHECK_GLIB2 means gio won't be in GLIB2_LIBS, which causes link
errors when trying to build spice-server.
Change inet_aton function to glib functions.
inet_aton only supported IPv4 addresses, and wasn't available on windows
machines. GInetAddress functions support IPv6 natively, and requires less
boilerplate code then IPv6 gettaddrinfo().
These macros were automatically appending the needed CFLAGS/LIBS to
variables passed as arguments. This is how spice-common uses them, but
now how spice-gtk/spice want to use them, and is making the macros more
complicated than they could (in particular this makes them use
AS_VAR_APPEND).
This is also not flexible enough as spice-gtk uses libcacard libraries,
while spice-common does not need them. If SPICE_CHECK_SMARTCARD
unconditionnally libcacard libraries to the variable spice-common passes
it as an argument, we'll end up linking with an unneeded library.
This commit removes this automatic appending from the SPICE_CHECK_*
macros and moves it to spice-common as it's the only one which needs it.
In mingw builds, this will be set to mingw-pkg-config rather than the
host system one. This is fixing a build failure on mingw when
spice-protocol is only installed in the mingw prefix and not
system-wide.
The linearization optimization that avoids copying only one item must
check that there are no further marshallers in the chain.
Just to be clear, we are trying to marshall a message like this:
message {
uint32 data_size;
uint64 *data[data_size] @marshall;
} SomeData;
Where the data field points to an array in dynamic memory. Marshalling
and demarshalling functions look good. The marshalling function creates
a submarshaller for the data field and links it to the root marshaller.
But when it comes to sending the data through the wire, only the
data_size field gets sent. We have observed that, in
spice_marshaller_linearize, execution enters into the optimization that
avoids copying the data when the root marshaller only has one item, but
it ignores the following marshallers in the list. Checking if there are
more marshallers fixes the problem.
Now that spice-protocol ships the needed .proto files as well as the
corresponding python scripts, spice-common can use these in order to
generate the C code for the SPICE (de)marshallers.
spice-protocol is a separate project which is having releases, so there
is no need to have a private spice-protocol copy in each spice-common
user, especially as after installation, the system-wide spice-protocol
copy will be used instead of the private one the module was built
against.
This patch changes the type of 'valid_attributes' and
'attributes_with_arguments'.
Both of them are list of different strings and are kept in sets.
This was the intention of the original code, but this patch
use a specific set([ strings ]) format, instead of { strings }.
This fixes the build for me on RHEL-6 (python-2.6.6).
Build error is:

This is to prepare to generate the wireshark dissector which uses
glib types instead of the newer C ones (for compatibility with some
compilers).

Verify that the attribute is known. This could help for instance to
avoid some future typo mistakes.
We also now have a list of attributes that we can comment for
documentation purpose.

Trying to generate enums.h with python3 results in
Traceback (most recent call last):

if len(messages) == 0:
TypeError: object of type 'filter' has no len()
filter() returns an enumerator object in python3 while it used to return
a list in python2. Using list(filter()) instead fixes that error.
I've checked that the generated enums.h is identical with python2 and
python3.
Runtime conversion from a string to uint32 is storing the magic with the same
endianness on both LE and BE machines. This requires aditional byte swap
when sending magic between LE/BE machines.
Changing quic magic to a constant will ensure, that it will be always stored in
native endianness, and the second byte swap won't be needed.
Commit d39dfbfe changes lz magic to be always treated as LE when encoded.

Update enums.h for preferred compression message
Add a preferred compression capability
When accessing a virtual desktop from different devices, some may have
different image compression requirements, e.g. slow devices may prefer
the faster LZ4 over GLZ. This message instructs the server to switch the
image compression algorithm. This patch also promotes the
SPICE_IMAGE_COMPRESS_* constants so that they are available from both
the server and the client.
