Retrying all tests is more likely to result in a different set of tests
failing the second time. This change makes sure only the failed tests are
retried.
"All rights reserved" was incorrect. The project was licensed under GPL3,
which means a lot of rights are licensed to everybody in the world, i.e.
not reserved to the "Tox Project".
this updates the version-sync script to generate proper SO versions
which will be used by cmake and libtool to create version symlinks
on the system when a library is installed as well as setting the SO
version in the binary.
To see what this does, you have to configure tox with a prefix:
./configure --prefix=/tmp/tox-with-libtool
mkdir cbuild && cd cbuild && cmake -DCMAKE_INSTALL_PREFIX=/tmp/tox-with-cmake ..
Then run `make && make install`.
in both instances you should see the following installed in `lib/`:
libtoxcore.so -> libtoxcore.so.1.4.0
libtoxcore.so.1 -> libtoxcore.so.1.4.0
libtoxcore.so.1.4.0
inside the binary the soname should be the one with .1 and it should not
contain the full version:
$ objdump -p libtoxcore.so.1.4.0 | grep SONAME
SONAME libtoxcore.so.1
We want to use the same libtool style .so versions in both build systems,
ideally both systems should read the version information from the same
configuration file.
This commit introduces an so.version configuration file and sets up
the autotools to use it.
The version numbers in so.version define the ABI compatibility and should be
updated prior to each release.

Previously, toxcore would send a kill control to the friend only if the
file control was valid. Determining which file transfer is used does not
depend on the specific file control. We can always kill it in that case.
Also, added some logging for file control logic, since there is no other
feedback on error (failure of the file control handler is swallowed).
On x86 and x86_64, this change has no effect. On IA64, this fixes a
potential hardware exception. A function returned a partially initialised
value of aggregate type. The only caller of this function checks that the
value is valid before accessing it by testing the one definitely
initialised member. Therefore on x86 and derived architectures, there is
no uninitialised memory access. On IA64, with the regular calling
convention, the struct is allocated on the caller stack and passed as a
pointer, so there the uninitialised memory is also never accessed.
However, on calling conventions where one or more struct members past the
first byte are passed in registers or copied in memory, this call can
cause undefined behaviour.
Specifically, the value can contain a trap representation of the integers
(at the very least the 16 bit port) and cause a hardware exception and
SIGFPE in userland.
Regardless of the explanation above, this change fixes an instance of
undefined behaviour that just happened to be OK on all systems we tested
on.
Previously, the `ipv6` variable was initialised to `-1`, but that value
was never read. Either it was set to 0 or 1, or the function would return
before it was read. Thus, I've changed it to uninitialised `bool is_ipv4`
(inverted semantics to avoid negative conditions `if (!is_ipv6)`).
The `pack_ip_port` function is a bit unfortunate, but I'm not rewriting
it until we have a binary writer (I'd be rewriting it twice).
