Export gProfiler-needed functionality from asprof

[marcin-ol]

Experimental merge of upstream changes to async-profiler.
Implement changes necessary to support upcoming features (esp. binary launcher - asprof) in gprofiler.

This is approach 1 - adding jattach passthru in asprof launcher.

@marcin-ol I pushed the rebase to async-profiler-granulate, I'm not sure the rebase is perfect - will validate it later - meanwhile you can re-base your branch on it and add your commits?

@marcin-ol , I fixed the rebase again so please re-apply the 2 commits of yours. Now it's ready from my end.

This is the full range-diff of the rebase for reference.

What's gone as part of this rebase is Add accept timeout as 3rd parameter of fdtransfer - let's make sure your upgraded version supports the same behavior?

Other than that change, other parts should be alright and I trust our tests.

I did another review round. Left a bunch of small comments. Also, I re-reviewed my rebase. All looks good! Let's finish those and merge it :)
