Pull request description:
Includes known Valgrind warnings in our dependencies that cannot be fixed in-tree.
Example use:
```
$ valgrind --suppressions=contrib/valgrind.supp src/test/test_bitcoin
$ valgrind --suppressions=contrib/valgrind.supp --leak-check=full \
--show-leak-kinds=all src/test/test_bitcoin --log_level=test_suite
```
Running with the suppressions file under Ubuntu 16.04:
```
$ valgrind --suppressions=contrib/valgrind.supp --leak-check=full --show-leak-kinds=all src/test/test_bitcoin --log_level=test_suite --run_test=wallet_crypto

Utility to generate the pnSeed[] array that is compiled into the client.
Build Tools and Keys
Debian
Contains files used to package bitcoind/bitcoin-qt for Debian-based Linux systems. If you compile bitcoind/bitcoin-qt yourself, there are some useful files here.
Gitian-descriptors
