rSTAGING7cfc38d37a8f: remove SCRIPT_ENABLE_SCHNORR flag and clean up tests
rABC7cfc38d37a8f: remove SCRIPT_ENABLE_SCHNORR flag and clean up tests

Summary

This is a backing-out of D2430, which added an impotent
SCRIPT_ENABLE_SCHNORR flag along with a bunch of duplicate tests. Now that
the flag is once again impotent, we remove it.

In addition to removing those tests, there were numerous other script_tests
cases that are now redundant as well, also removed in this diff.

Depends on D3331

1581	Just an observation: No one noticed the typo (errand space): `, " 0x21`

1581	Heh nice catch, I wonder how that happened ...

markblundeberg mentioned this in D3331: remove effect of SCRIPT_ENABLE_SCHNORR flag.Jun 23 2019, 16:17

Don't use 0 for flags.

src/test/script_tests.cpp
1446	Dn't use 0 here, there is a flag none or something.
1692	Why is this one removed?

This revision now requires changes to proceed.Jun 25 2019, 23:04

src/test/script_tests.cpp
1692	This is just an ECDSA signature check, originally inserted to make sure ECDSA still works with ENABLE_SCHNORR flag on. Now that the flag is gone I figured we don't need to keep it around. (this is the case for many other removed tests as well)

src/test/script_tests.cpp
1446	Yeah there is `SCRIPT_VERIFY_NONE`, however that doesn't get used at all in this script_tests.cpp file (in fact very few places in the codebase use it). If you like I can substitute that for 0 in these tests, alternatively I can do a follow-up where all the 0 are substituted in all the tests.

It all looks good to me.

I think changing the test flag from 0 to NONE should be done in a separate Diff.

src/test/script_tests.cpp
1446	I noticed this also when I was doing the Segwit Recovery Diffs. Although the `NONE` flag exists for these tests, it is currently unused. I agree that this should be changed, but it should be in a separate Diff that changes all instances together IMO.
