Expand the set of things SetInlineDataFormat accepts Extension scripts (a/k/a "plugins") can now apply any data format supported by FormatDescriptor to inline data. In particular, it can now handle variable-length inline strings. The code analyzer verifies the string structure (e.g. null-terminated strings have exactly one null byte, at the very end). Added PluginException to carry an exception back to the plugin code, for occasions when they're doing something so wrong that we just want to smack them. Added test 2022-extension-scripts to exercise the feature.

Fix bug in inline JSR/JSL no-continue handling JSR/JSL calls with inline data have the option of reporting that they don't continue, which causes the code analyzer to treat them as JMPs instead. There was a bug that was causing the no-continue flag to be lost in certain circumstances. The code now explicitly records the plugin's response in an Anattrib flag. Test 2022-extension-scripts has been updated with a test case that exercises this situation.

Optionally treat BRKs as two-byte instructions Early data sheets listed BRK as one byte, but RTI after a BRK skips the following byte, effectively making BRK a 2-byte instruction. Sometimes, such as when diassembling Apple /// SOS code, it's handy to treat it that way explicitly. This change makes two-byte BRKs optional, controlled by a checkbox in the project settings. In the system definitions it defaults to true for Apple ///, false for all others. ACME doesn't allow BRK to have an arg, and cc65 only allows it for 65816 code (?), so it's emitted as a hex blob for those assemblers. Anyone wishing to target those assemblers should stick to 1-byte mode. Extension scripts have to switch between formatting one byte of inline data and formatting an instruction with a one-byte operand. A helper function has been added to the plugin Util class. To get some regression test coverage, 2022-extension-scripts has been configured to use two-byte BRK. Also, added/corrected some SOS constants. See also issue #44.

Correctly handle embedded instruction edge case This began with a change to support "BRK <operand>" in cc65. The assembler only supports this for 65816 projects, so we detect that and enable it when available. While fiddling with some test code an assertion fired. This revealed a minor issue in the code analyzer: when overwriting inline data with instructions, we weren't resetting the format descriptor. The code that exercises it, which requires two-byte BRKs and an inline BRK handler in an extension script, has been added to test 2022-extension-scripts. The new regression test revealed a flaw in the 64tass code generator's character encoding scanner that caused it to hang. Fixed.

Mark flags as indeterminate for inline BRK We weren't altering the status flags after a BRK because of the assumption that a BRK was a crash. For an inline BRK, such as a SOS call, execution continues. We need to mark NVZC indeterminate or we may incorrectly handle conditional branches that follow. The BRK instruction now uses the same flag updater as JSR, since it's effectively a subroutine call to unknown code. If execution doesn't continue across the BRK then the flags don't matter. Updated 20182-extension-scripts to exercise this.
