pkg/mount: implement/use filter for mountinfo parsing Functions `GetMounts()` and `parseMountTable()` return all the entries as read and parsed from /proc/self/mountinfo. In many cases the caller is only interested only one or a few entries, not all of them. One good example is `Mounted()` function, which looks for a specific entry only. Another example is `RecursiveUnmount()` which is only interested in mount under a specific path. This commit adds `filter` argument to `GetMounts()` to implement two things: 1. filter out entries a caller is not interested in 2. stop processing if a caller is found what it wanted `nil` can be passed to get a backward-compatible behavior, i.e. return all the entries. A few filters are implemented: - `PrefixFilter`: filters out all entries not under `prefix` - `SingleEntryFilter`: looks for a specific entry Finally, `Mounted()` is modified to use `SingleEntryFilter()`, and `RecursiveUnmount()` is using `PrefixFilter()`. Unit tests are added to check filters are working.
