376f4929f8f75011b72b2f9c3164980db482278a build: disable BIP70 support by default (fanquake)
Pull request description:
Disable BIP70 support in the GUI by default for `0.19.0` (for eventual removal in `0.20.0`?).
Users who want to compile with BIP70 support enabled can pass `--enable-bip70` to `./configure`.
I've inverted the current `--disable-bip70` test to instead pass `--enable-bip70`.
Tested configurations on `macOS` (`protobuf` installed with `brew`).
Protobuf available and `./configure`:
```
Options used to compile and link:
with wallet = yes
with gui / qt = yes
with bip70 = no
```
Protobuf available and `./configure --enable-bip70`:
```
Options used to compile and link:
with wallet = yes
with gui / qt = yes
with bip70 = yes
```
Protobuf not available (i.e `brew unlink protobuf`) and `./configure`:
```
Options used to compile and link:
with wallet = yes
with gui / qt = yes
with bip70 = no
```
Protobuf not available and `./configure --enable-bip70`:
```
checking whether to build test_bitcoin-qt... yes
checking whether to build BIP70 support... configure: error: protobuf missing
```
TODO:
- [x] Remove `protobuf` from other Travis builds
- [ ] Documentation updates (mention that `protobuf` is now optional)?
- [ ] Could split release notes into GUI and build
