---------------------------------------

             Assignee: Pavel Kovalenko  (was: Andrey Gura)
        Fix Version/s: 2.6
    Affects Version/s: 2.5

[~agura] Tests with MMap are fixed.
There are also several fixes in WAL manager:
1) Unpark waiters in finally block
2) Usages of "envFailed" in Fsync WAL manager were correctly replaced with cctx.invalid()
check.

> Currently tests 4 are failed in  PDS 2 suite with timeout:
>       IgnitePdsTestSuite2: IgniteWalFlushBackgroundWithMmapBufferSelfTest.testFailAfterStart
(fail rate 100,0%) 
>       IgnitePdsTestSuite2: IgniteWalFlushBackgroundWithMmapBufferSelfTest.testFailWhileStart
(fail rate 100,0%) 
>       IgnitePdsTestSuite2: IgniteWalFlushLogOnlyWithMmapBufferSelfTest.testFailAfterStart
(fail rate 100,0%) 
>       IgnitePdsTestSuite2: IgniteWalFlushLogOnlyWithMmapBufferSelfTest.testFailWhileStart
(fail rate 100,0%) 
> Tests were introduced in ticket [IGNITE-7809]. 
> Tests try to emulate failure using exceptions in file IO, but MMap-ed modes does not
allow currently to be tested with current tests approach.
> It is suggested to create new testing opportunities for MMap modes.
