The native binaries generated in the depends system are available on the path,
but system binaries are still visible. This change ensures we use cargo from
the depends system rather than whatever might be installed locally.
The only upstream change relative to the previous commit is that the
various Zcash-specific dependencies have been pulled into a cargo
workspace. The dependecies in the workspace use the same commits as the
crates we had previously vendored.
The patches are necessary to handle the fact that cargo requires that
dev dependencies are available even if not used, and we would otherwise
need to vendor all the underlying crates.
Add filename and SHA256 hash for Windows Rust package
When running `make download` in the `depends` directory, the `download-win` target (which `download` depends on) generates an error when it runs the commands defined in `check_or_remove_sources`:
```Makefile
sha256sum: /home/vagrant/zcash/depends/work/download/rust-1.16.0/..hash: no properly formatted SHA256 checksum lines found
funcs.mk:242: recipe for target '/home/vagrant/gitian-builder/cache/common/download-stamps/.stamp_fetched-rust-.hash' failed
make[1]: *** [/home/vagrant/gitian-builder/cache/common/download-stamps/.stamp_fetched-rust-.hash] Error 1
make[1]: Leaving directory '/home/vagrant/zcash/depends'
Makefile:153: recipe for target 'download-win' failed
make: *** [download-win] Error 2
```
The reason for the error is that `depends/packages/rust.mk` defines `rust_file_name_linux` and `rust_file_name_darwin` but leaves `rust_file_name_mingw32` undefined.
A directory of available rust downloads is here: https://static.rust-lang.org/dist/index.html
The closest windows analog in that list (using the same version number as currently defined in `rust.mk`) appears to be `rust-mingw-1.16.0-x86_64-pc-windows-gnu.tar.gz`. A corresponding sha256 value is also given in `rust-mingw-1.16.0-x86_64-pc-windows-gnu.tar.gz.sha256`.
After adding these values to `rust.mk`, the rust-mingw tar package was downloaded along with the rest of the dependencies and the above error message went away.
Closes#2279. Configures CMake to enable C++11, build static libaries
and only build cpp bindings with minimal dependencies. Documentation,
examples, tests and other language bindings are no longer built.
CMake will no longer try to find commands and packages which are not
required for building the target.
Debian 8 stable ships with gcc 4.9.2 and cmake 3.0.2. Previously
the depends package used CMAKE_CXX_STANDARD to tell cmake to use
C++11, but the option requires cmakes 3.1+. To resolve the issue
we now update relevant CMakeLists.txt and set CMAKE_CXX_FLAGS.
Add a patch that seems to be necessary for compatibilty of libevent
2.0.22 with recent mingw-w64 gcc versions (at least GCC 5.3.1 from Ubuntu
16.04).
Without this patch the Content-Length in the HTTP header ends up as
`Content-Length: zu`, causing communication between the RPC
client and server to break down. See discussion in #8653.

Thanks to @sstone for the suggestion.
V1.0.0 rc1 gitian
Removes indeterminism from gitian builds: underlying processor instruction set variant of x86_64 was being detected by the libgmp autoconf process, which caused differences in libgmp and libsnark
bdb 6.X was released under the AGPL, which is incompatible with MIT-licensed
software (the result must be licensed under AGPL). bdb 5.X uses the same license
as bdb 4.8, and thus retains the same compatibility as in upstream Bitcoin.
Thanks to Luke-Jr for raising this issue.
These flags are potentially risky, because they require that the app explicitly
initialize stuff that it wouldn't otherwise need to initialize, and we don't
have time for the necessary review.
