If the `libqt4-dev` package is installed it picks the moc executable
from the system instead of our custom-built one. This results in
compatibility errors.

This commit convinces configure to pick the right one.

e27c4110 Remove build-time no-IPv6 setting (Wladimir J. van der Laan)

c0e0b05a Bugfix: configure: Look in libx32 subdirectory for boost libraries (Luke Dashjr)

Cleaned up wording and spacing for readability.

The year is 2014. All supported operating systems have IPv6 support,
most certainly at build time (this doesn't mean that IPv6 is configured,
of course).

If noone is exercising the functionality to disable it, that means it
doesn't get tested, and IMO it's better to get rid of it.

(it's also not used consistently in RPC/boost and Net code...)

Last update (48be9cea) missed quite a lot, for some reason.

This is also the first update done with the new script
`contrib/devtools/update-translations.py`

Run this script from the root of the repository to update all translations from transifex.
It will do the following automatically:

- create a transifex configuration file
- fetch all translations
- post-process them into valid and committable format

This is a project-wide configuration file and should be the same for
everyone.
Also remove mention of creating it yourself from the translation process.

1cc7f54a use standard __func__ instead of __PRETTY_FUNCTION__ (Philip Kaufmann)

After last commit, our executables should export no symbols anymore.  To
make sure that this stays the case, verify this in the symbol checker
script.

This avoids conflicts between the libraries statically linked into bitcoin and any
libraries we may link dynamically (such as Qt and OpenSSL, see issue #4094).
It also avoids start-up overhead to not export any unnecessary symbols.
To do this, build a linker script that marks all symbols as local.

Should make it possible to run the resulting GUI executable on
Linux distributions that use Qt 4.6, such as Debian Wheezy and Tails.

Builds a mini-SDK for building against Qt 4.6. This includes the headers
as well as host utilities such as `lrelease`, `qrc` and `moc`.

This speeds up the gitian build a bit - libqt4-dev pulled in a lot of packages,
and is no longer needed as this provides a replacement of our own.

Note: This does not replace the Qt build with at static library. After this
commit we still build dynamically against the system Qt library. The only
difference is that compatibility with an older version is maintained. This
loses minor GUI functionality (such as setPlaceholderText) but still
allows integration into the window management of the host OS, unlike
when statically linking.

Update English translation from source code, and pull other translations
from Transifex.

74fc254c devtools: add script to check symbols from Linux gitian executables (Wladimir J. van der Laan)

6e40fcf4 Update contrib/debian for autotools, among a few other tweaks (Matt Corallo)

Add a script to check that the (Linux) executables produced by gitian
only contain allowed gcc, glibc and libstdc++ version symbols.  This
makes sure they are still compatible with the minimum supported Linux
distribution versions.

bb1f1c90 [Qt] importwallet progress (Cozz Lovan)

This avoids the GUI from getting stuck on
periodical polls if the core is holding the locks for a longer time -
for example, during a wallet rescan.

Unit tests with DEBUG_LOCKORDER were running into assertions.
