rc: use proper type for storing ulimit values rc on amd64 stores ulimit values as 32-bit int, but the limits on OpenBSD amd64 can exceed 2^31, so "ulimit -a" shows some values as negative. This is a problem when I want to increase my ulimit but the hard ulimit values are printed as negative.

acme: preserve window position and selection during Get Before, executing Get in a file rewound the window offset and selection to the start of the file. After this CL, Get preserves the window offset and selection, where preserve is defined as "the same line number and rune offset within the line". So if the window started at line 10 before and the selection was line 13 chars 5-7, then that will still be true after Get, provided the new content is large enough. This should help the common situation of plumbing a compiler error, realizing the window is out of date, clicking Get, and then losing the positioning from the plumb operation.

acme: check file content before declaring file "modified since last read" Bad remote file systems can change mtime unexpectedly, and then there is the problem that git rebase and similar operations like to change the files and then change them back, modifying the mtimes but not the content. Avoid spurious Put errors on both of those by checking file content. (False positive "modified since last read" make the real ones difficult to notice.)

devdraw: fix build on macOS < 10.12 After making the build on macOS silent on commit 310ae03, the build was broken on macOS lesser than 10.12 (Sierra). This commit conditionally checks the version the of the SDK before using the defined values for silent build. Fixes #66.
