a1b50051ed mcexec: always compile debug statements 
This helps catching errors like accessing a field that no longer exists
in a debug print that wasn't compiled...

aaa246f86f mcexec: change debug printf macros to be more tolerant to trivial format 
Enabling DEBUG fails to compile. It'd be easy to fix the dprintf to dprint
but this is just as generic and we can now use dprintf everywhere

be4d84c0c1 mcexec: Add --stack-premap=<premap_size>[,<max>] 
<premap_size> of stack is pre-mapped on creating a process.
And its max size of stack is set to <max>.
This replaces MCKERNEL_RLIMIT_STACK=<premap_size>,<max>.

38961fca78 Revert "do_fork(): RLIMIT_NPROC check" 
This reverts commit 035e7913d8.

035e7913d8 do_fork(): RLIMIT_NPROC check 
1. mcexec sets RLIMIT_NPROC to the number of mcexec threads.
2. do_fork() gets the current number of threads by calling rusage function.
3. do_fork() returns -EAGAIN when the limit is exceeded.
