Homu 4eb3dc7ec6 Auto merge of #4321 - str4d:internalise-rust, r=str4d 
Bring the librustzcash crate into this repository

Rust dependencies are now canonically pinned within this repository by
`Cargo.lock`. We continue to use the depends system for vendoring the
dependencies, to ensure our Gitian builds continue to function (which have
no network access at build time, and fetch dependencies separately).

The `--enable-online-rust` configure flag replicates the behaviour of the
`LIBRUSTZCASH_OVERRIDE` environment variable (enabling the build system to
use https://crates.io instead of vendored dependencies).

This pulls in the exact version of `librustzcash` that we currently depend on
(corresponding to the `0.1.0` tag in https://github.com/zcash/librustzcash).
The changes to the crate since then will be pulled in as a separate PR.

Part of zcash/librustzcash#155.
Part of #4230.

Usage

To build dependencies for the current arch+OS:

make

To build for another arch/OS:

make HOST=host-platform-triplet

For example:

make HOST=x86_64-w64-mingw32 -j4

A prefix will be generated that's suitable for plugging into Bitcoin's configure. In the above example, a dir named x86_64-w64-mingw32 will be created. To use it for Bitcoin:

./configure --prefix=`pwd`/depends/x86_64-w64-mingw32

Common host-platform-triplets for cross compilation are:

  • i686-w64-mingw32 for Win32
  • x86_64-w64-mingw32 for Win64
  • x86_64-apple-darwin11 for MacOSX
  • arm-linux-gnueabihf for Linux ARM

No other options are needed, the paths are automatically configured.

Dependency Options: The following can be set when running make: make FOO=bar

SOURCES_PATH: downloaded sources will be placed here
BASE_CACHE: built packages will be placed here
SDK_PATH: Path where sdk's can be found (used by OSX)
PRIORITY_DOWNLOAD_PATH: Try fetching source files from here before using their own URLs
NO_WALLET: Don't download/build/cache libs needed to enable the wallet
DEBUG: disable some optimizations and enable more runtime checking
LIBRUSTZCASH_OVERRIDE: Path to a local librustzcash repository

If some packages are not built, for example make NO_WALLET=1, the appropriate options will be passed to bitcoin's configure. In this case, --disable-wallet.

Additional targets:

download: run 'make download' to fetch all sources without building them
download-osx: run 'make download-osx' to fetch all sources needed for osx builds
download-win: run 'make download-win' to fetch all sources needed for win builds
download-linux: run 'make download-linux' to fetch all sources needed for linux builds
