devproc: fix proccrlmemio bugs
dont kill the calling process when demand load fails if fixfault()
is called from devproc. this happens when you delete the binary
of a running process and try to debug the process accessing uncached
pages thru /proc/$pid/mem file.
fixes to procctlmemio():
- fix missed unlock as txt2data() can error
- make sure the segment isnt freed by taking a reference (under p->seglock)
- access the page with segment locked (see comment)
- get rid of the segment stealer lock
other stuff:
- move txt2data() and data2txt() to segment.c
- add procpagecount() function
- make return type mcounseg() to ulong
