Kir Kolyshkin cb58aa84d6 prepare_pstree: fixup reading kernel pid_max 
Two fixes (reported by coverity) and a minor nitpick:

1. Fix checking error from open_proc().

2. Fix buffer overflow. MAX_ULONG can be 20 characters long, so
ret = read() can return 20 and buf[ret] = 0 will overrun the buf.
Make a buf one character longer (an extra byte for \0) and pass
sizeof(buf) - 1 to read to fix it.

3. Call close() right after read().

This is a fixup to commit e68bded.

Reported by Coverity, CID 168505, 168504.

CRIU (Checkpoint and Restore in Userspace)

An utility to checkpoint/restore tasks. Using this tool, you can freeze a running application (or part of it) and checkpoint it to a hard drive as a collection of files. You can then use the files to restore and run the application from the point it was frozen at. The distinctive feature of the CRIU project is that it is mainly implemented in user space.

The project home is at http://criu.org.
