Notable changes

Build system

The --enable-lcov, --disable-tests, and --disable-mining flags for zcutil/build.sh have been removed. You can pass these flags instead by using the CONFIGURE_FLAGS environment variable. For example, to enable coverage instrumentation (thus enabling "make cov" to work), call:
```
CONFIGURE_FLAGS="--enable-lcov --disable-hardening" ./zcutil/build.sh
```
The build system no longer defaults to verbose output. You can re-enable verbose output with ./zcutil/build.sh V=1
