13298d90a9 Silence spurious clang warnings
Silence clang warnings under --enable-expensive-hardening, including:
  + implicit truncation of 64 bit values to 32 bit;
  + const char assignment to self;
  + tautological compare; and
  + additional parentheses around equality tests. (gcc uses these to
    silence assignment, so clang warns when they're present in an
    equality test. But we need to use extra parentheses in macros to
    isolate them from other code).

3b7d0ed08e Use trunnel for crypto_pwbox encoding/decoding.
This reduces the likelihood that I have made any exploitable errors
in the encoding/decoding.

This commit also imports the trunnel runtime source into Tor.

8184839a47 Rudimentary-but-sufficient passphrase-encrypted box code.
See crypto_pwbox.c for a description of the file format.

There are tests for successful operation, but it still needs
error-case tests.
