split client and server builds

[Antoine Martin]

Make it possible to install just the client or just the server.
For rpm packaging, this probably means having:

• xpra: meta package
• xpra-common: unchanged, common bits
• python2-xpra-common: the python2 code used by both client and server
• python2-xpra-server: the python2 server code
• python2-xpra-gtk-client: the current pygtk client

Not shown here: python3

For win32 and OSX, this means having 3 different types of builds:

• full - same as today
• client only
• server only

See also #1258.

r14547 moves the html5 client to its own package so we can update it separately: xpra-html5.

Too late for this sort of structural change, re-scheduling.

As per ​xpra - ImportError: No module named client.gtk2.client, people will get confused if they install a "server-only" build or package and find that they cannot run "xpra info" or "xpra stop".

So maybe we will need an "python2-xpra-client-cli" package? (and rename "python2-xpra-client-gtk2"). We should be able to use the "python3" version of the package for those, in our endless efforts to move away from python2.

• r15333 improves the error message when trying to run the client or server and its python components are not installed
• r15334 splits the RPM into multiple packages

New sub packages:

• "xpra" meta package that installs everything (so upgrades will continue to work)
• "xpra-common": man page, base config files, icon, etc
• "xpra-common-client": client config files, .desktop files, mime entry
• "xpra-common-server": server config files, systemd unit file, tmpfiles.d, cups backend, xorg config, cuda+nvenc configs, .. triggers SSL key generation on install, firewall rules
• "python2-xpra-common": common python2 modules
• "python2-xpra-client": python2 xpra client
• "python2-xpra-server": python2 xpra X11 server
• "python3-xpra-common": common python3 modules
• "python3-xpra-client": python3 xpra client (limited)
• "python3-xpra-server": python3 xpra X11 server (limited)

Remaining issues:

• shadow server complains that "no system tray implementation available" if the client package is not installed - this needs to be moved to "common"
• websockify is not available with python3 (only in Fedora rawhide)
• Debian packaging? (meh)
• win32 and osx

r15341 renames "python2-xpra-common" to just "python2-xpra" to resolve conflicts when upgrading on centos7

MS Windows

r15342 + r15343 add the ability to build "client only" win32 builds using:

sh win32/PY27_MINGW_BUILD.sh CLIENT /silent

Beta builds uploaded: http://xpra.org/beta/windows/

---

Mac OSX

mostly done in r15344 using:

CLIENT_ONLY=1 DO_TESTS=0 ./make-all.sh

Both the client builds and the regular full builds should be parallel installable, though there may be some conflicts:

• both apps will claim the mimetype
• both apps contain an Xpra_NoDock.app sub app with the same app id

Beta builds uploaded: http://xpra.org/beta/osx/

RPM

r15346:

• splits printing dependencies between client and server packages
• adds "python[23]-xpra-audio" packages so we can install the gstreamer sink + source without the client or server, or install the client or server without audio forwarding
• makes the html5 package optional: you can install a server without it

PS: upgrades from previous 2.1 snapshots may or may not work (the "python[23]-xpra-common" is no more and may conflict)

---

I think this will do for this release.
@smo: not sure you care - feel free to just close, but the ability to install a more minimal python3 build for sound forwarding is nice (we could take this further and split "bus", "codecs", etc... probably not worth the pain)

[Antoine Martin]

FYI: r15672 also introduces ​weak dependencies, available since Fedora 21 - sadly not available in centos7. (was only added in ​RPM 4.12)

[Antoine Martin]

r15684 restores the ability to take screenshots in client-only builds - but maybe this should still be optional?

crickets - works for me
