527e8ca7b54515e129484824e4df66b5dafdb45f test: Remove outdated comment in script_tests (billymcbip)
Pull request description:
1. Remove a comment referencing a file that no longer exists in the codebase: `script_invalid.json`.
2. Fix a test that isn't implemented as intended. The idea is to test execution order by providing a signature that would cause script failure when parsed. An empty signature does not cause script failure in `CHECKMULTISIG`. Use `OP_1` for the second signature instead of `OP_0`.
3. Copy existing `STRICTENC` tests and change the flag to `DERSIG`. `DERSIG` is a consensus flag (unlike `STRICTENC`), so it'd be good to have dedicated test cases.
`script_tests` pass on my end.

0ca4dcd78665bc5258a2b9cfcef0dcdf971a88c3 script: add SCRIPT_ERR_SCRIPTNUM error (Bruno Garcia)
Pull request description:
When evaluating a script, the current code is bad for analyzing some errors because it returns `SCRIPT_ERR_UNKNOWN_ERROR` for errors that are clearly known.
`CScriptNum` has two well defined errors: number overflow and non-minimally encoded number. However, for both errors we return as unknown. This PR changes it by adding a new ScriptError that is used for any `CScriptNum` error.

Pull request description:
This was introduced by commit ab9edbd6b6eb3efbca11f16fa467c3c0ef905708.
It appears the original author may have gotten tired and pasted the wrong error code into this 1 place. Every other situation where the value stack lacks the required number of arguments for the op-code, SCRIPT_ERR_INVALID_STACK_OPERATION is reported. Not so here.
This commit fixes the situation.
EDIT: Note this turns out to be a dupe of the abandoned #30359 .

Empty public keys in tapscript are rejected by consensus rules, independent of SCRIPT_VERIFY_STRICTENC. Add SCRIPT_ERR_TAPSCRIPT_EMPTY_PUBKEY to distinguish this from STRICTENC policy failures currently reported as SCRIPT_ERR_PUBKEYTYPE.
This commit creates new test utilities for future Taproot script
tests within script_tests.json. The key features of this commit are the
addition of three new tags: `#SCRIPT#`, `#CONTROLBLOCK#`, and
`#TAPROOTOUTPUT#`. These tags streamline the test creation process by
eliminating the need to manually generate these components outside the
test suite.
* `#SCRIPT#`: Parses Tapscript and outputs a byte string of opcodes.
* `#CONTROLBLOCK#`: Automatically generates the control block for a given
Taproot output.
* `#TAPROOTOUTPUT#`: Generates the final Taproot scriptPubKey.

It appears the original author may have gotten tired and pasted the wrong

1e747e3c1e Make segwit failure due to CLEANSTACK violation return a SCRIPT_ERR_CLEANSTACK error code. (Mark Friedenbach)
Pull request description:
If a segwit script terminates with a stack size not equal to one, the current error code is EVAL_FALSE. This is semantically wrong, and prevents explicitly checking CLEANSTACK violations in the unit tests. This PR changes the error code (and affected unit tests) to use SCRIPT_ERROR_CLEANSTACK instead of SCRIPT_ERROR_EVAL_FALSE.

01013f5 Simplify tx validation tests (Pieter Wuille)
2dd6f80 Add a test that all flags are softforks (Pieter Wuille)
2851b77 Make all script verification flags softforks (Pieter Wuille)
Pull request description:
This change makes `SCRIPT_VERIFY_UPGRADABLE_NOPS` not apply to `OP_CHECKLOCKTIMEVERIFY` and `OP_CHECKSEQUENCEVERIFY`. This is a no-op as `UPGRADABLE_NOPS` is only set for mempool transactions, and those always have `SCRIPT_VERIFY_CHECKLOCKTIMEVERIFY` and `SCRIPT_VERIFY_CHECKSEQUENCEVERIFY` set as well. The advantage is that setting more flags now always results in a reduction in acceptable scripts (=softfork).
This results in a nice and testable property for validation, for which a new test is added.
This also means that the introduction of a new definition for a NOP or witness version will likely need the following procedure (example OP_NOP8 here)
* Remove OP_NOP8 from being affected by `SCRIPT_VERIFY_DISCOURAGE_UPGRADABLE_NOPS`.
* Add a `SCRIPT_VERIFY_DISCOURAGE_NOP8`, which only applies to `OP_NOP8`.
* Add a `SCRIPT_VERIFY_NOP8` which implements the new consensus logic.
* Before activation, add `SCRIPT_VERIFY_DISCOURAGE_NOP8` to the mempool flags.
* After activation, add `SCRIPT_VERIFY_NOP8` to both the mempool and consensus flags.

That OP_NOP10 is the last executable opcode is a bit of a obscure trivia, and the MAX_OPCODE constant already exists. This merely standardizes use of MAX_OPCODE over OP_NOP10 where it makes sense and is more clear.
A few "a->an" and "an->a".
"Shows, if the supplied default SOCKS5 proxy" -> "Shows if the supplied default SOCKS5 proxy". Change made on 3 occurrences.
"without fully understanding the ramification of a command" -> "without fully understanding the ramifications of a command".
Removed duplicate words such as "the the".
mininode now supports witness transactions/blocks, blocktools
has a helper for adding witness commitments to blocks, and script
has a function to calculate hashes for signature under sigversion
1, used by segwit.
