Sometime we need sync points in testee program flow,
for this reason task_waiter_ introduced.
The call semantics is the following
Parent Child
------ -----
task_waiter_init
task_waiter_wait4
task_waiter_complete
task_waiter_wait4
task_waiter_complete
...
Thus initially task_waiter_init should be called
to initialize all internals guts needed.
Then one become waitee and calls for task_waiter_wait4,
where lockid should be provided as an argument. Since
it should be unique values the best option might be
gettid().
The same applies to a waiter side -- it should call
for task_waiter_complete and provide a lockid.

Will be fixed later.
Note, that the original /proc mount is kept as the dumping code requires
it for reading pagemap file with RSS info. Worth fixing it some day?

This test is very basic :( Need more work on it.
One note about --close arg to crtools -- bash leaves all
fds open when laucnhing progams, and for restore this is
critical, as one of them can be busy. Iterating over all
the possibel fds and closing them is "do not want" thing.

On some systems PAGE_SIZE is declared as sysconf(_SC_PAGESIZE) in <sys/user.h>
this is non-constant expression, so it cannot be used in type declarations.
This breaks compilation with a very non-obvious error message:
CC parasite-syscall.o
In file included from parasite-syscall.c:30:0:
./include/parasite.h:90:8: error: variably modified ‘fds’ at file scope
crtools doesn't uses anything from <sys/user.h>, so we can drop its usage.
