32da92bdf6 gitian: Improve error handling (Wladimir J. van der Laan)
Pull request description:
Improve error handling in gitian builds:
- Set fail-on-error and pipefail flag, this causes a command to fail when either of the pipe stages fails, not only when the last of the stages fails, so this improves error detection.
- Also use `xargs` instead of `find -exec`, because `find` will not propagate errors in the executed command, but `xargs` will.
This will avoid some issues like #15541 where non-determinism is silently introduced due to errors caused by environment conditions (such as lack of disk space in that case).

Release version strings were broken in Gitian by 7522. This is a minimal fix
suitable for 0.15.
After this, we should fix up version handling for good so that gitian packages
the correct string in the release tarball, so that git is not required to get
the tag name.

Also change the mac filename to match
The procedure remains the same, but now there's a nifty script to automate
the signing process.
Future steps:
- Build osslsigncode in the gitian-win descriptor so that the signer itself is
deterministic.
- Verify in the gitian-win-signer descriptor that the expected cert chain was
used.
The consistency is helpful for gauging Gitian build progress. Right now it's necessary to remember which platform builds in which order, which can be confusing if you're attempting to get a quick idea of how far along your builds are.
The -debug tarballs/zips contain detached debugging symbols. To use them, place
in the same dir as the target binary, and invoke gdb as usual.
Also, because the debug symbols add a substantial space requirement, the build
dirs are now deleted when they're no longer needed.
This removes the following executables from the binary gitian release:
- test_bitcoin-qt[.exe]
- bench_bitcoin[.exe]
@jonasschnelli and me discussed this on IRC a few days ago - unlike the
normal `bitcoin_tests` which is useful to see if it is safe to run
bitcoin on a certain OS/environment combination, there is no good reason
to include these. Better to leave them out to reduce the download
size.
Sizes from the 0.12 release:
```
2.4M bitcoin-0.12.0/bin/bench_bitcoin.exe
22M bitcoin-0.12.0/bin/test_bitcoin-qt.exe
```
Common sentiment is that the miniupnpc codebase likely contains further
vulnerabilities.
I'd prefer to get rid of the dependency completely, but a compromise for
now is to at least disable it by default.
For Gitian releases:
- Windows builds remain unchanged. libstdc++ was already linked statically.
- OSX builds remain unchanged. libstdc++ is tied to the SDK and not worth
messing with.
- Linux builds now statically link libstdc++.
For Travis:
- Match the previous behavior by adding --enable-reduce-exports as
necessary.
- Use static libstdc++ for the full Linux build.
Since permissions and timestamps are changed for the sake of determinism,
. must not be added to the archive. Otherwise, tar may try to modify pwd when
extracting.
