Yet another fix `GDBCLICommand >> #operation` Commit 03a17952 attempted to fix `GDBCLICommand >> #operation` but somehow the fix in `Operations` list initialization was not commited. This commit adds these changes and hopefully really fix the issue.

Pharo port: do not track and kill (!) processes spawn during test Checking and terminating forked processes once testcase finished (worse before `#tearDown` of resources!) is a very stupid idea as it effectively breaks code that spawn long-running service processes (like LibGDB's even pump or LibUnix's process reaper). At the very least this behavior should be controllable by the test case, in other words a particular test case shoul be able to opt-out (or better, opt-in). But well, it is not hence this hack. Sigh. This is really not LibGDBs specific hack and probably should belong elsewhere but since I (JV) do know better place for it as of now and since above problem would almost certainly manifest when using LibGDBs, I put it here (until better place would be found).

Compatibility: use `#assert:description:` instead of `#assert:message:` ...as the latter does not exist (at least) in Pharo.

Pharo port: add missing `AnnouncementSet >> handles:` ...that is needed if one wants (needs) to wait for one of two or more events, like in `GDBDebugger >> c`: ^ self send: 'continue' andWaitFor: GDBStoppedEvent , GDBThreadGroupExitedEvent

Compatibility: allow ports to customize semaphore / mutex creation This commit adds new port methods: `#newSemaphore` and `#newMutex`. This allows ports to return customized objects. This is needed to accomodate different implementations / behaviors of semaphores among dialects (e.g, Pharo)

Initialize UDIS86-based disassembler lazily

Compatiblity: do not access Exeption's `parameter` instvar directly ...but through an accessor. (At least) Pharo has no instvar `parameter`.

Pharo port: add new make target `source` This commit makes new target - `source` which only generates sources for Pharo. This is to be used from other (Pharo) projects using LibGDBs (e.g., Tinyrossa).

Pharo port: fix makefile This commit fixes an error when running Pharo's `make` in fresh clone caused by multiple attempts to clone smalltalk `makefiles`.

Add Pharo version of `GDBPortlib` ...that uses LibUnix from pharo-hacks [1]. Also, add dependency on `LibCompat` [1]: https://github.com/janvrany/pharo-hacks
