Add a new field to the package struct to hold PGP information and
instruct db_read to pick it up from the database. It is currently unused
internally but this is the first step.
Due to the fact that we store the PGP sig as binary data, we need to store

This is a rather serious data corruption issue that luckily manifested
itself today in a noticable way. A package in testing had replaces

happens when we hit the end of an archive block, do not have a newline,
and have to continue reading from the next block to complete the line.

Adding the CURLcode is necessary in order to return an error string from
pm_error. Unlike libfetch, curl returns numerical error numbers and does
not maintain a staticly allocated string with the last error generated.
Adding the curl object itself to the handle is advantageous (and
encouraged by curl_easy_perform(3)) because the handle is reusable for
successive operations. This cuts back on overhead when downloading
multiple files in a single transaction.

This allows error messages emitted by the frontend to be a bit more
descriptive and not have the annoying "well why didn't you tell me that
the first time" problem. If a package had multiple missing deps, we
would bail on the first one before rather than finish processing all
missing dependencies, and only print one error message. Instead,
continue through this entire set of missing deps and append all eventual
errors.
The added pactest tests this case, as the to be installed package has
two missing dependencies. However, pactest does not actually test or see
the difference in output from before and after, so it passes in both
cases, but it is clearly visible in the logs.

Turn it into an enum rather than a boolean, and use a bitmask like we do for
reading DB entries. The relevant flag is turned on in our two calculate
loops, and anything reading the used flag later can decided which flag (or
either) is relevant.
This will allow the read-only partition code to be triggered on a
remove-only operation, e.g. if /boot was read-only and one tried to remove
grub in a sync transaction. Of course, right now, we don't actually run the
diskspace check code in the '-R' codepath.

This is a bit of a stopgap solution for the problem, but an easier one than
revamping the file conflict checking code to support the same stuff. Using
some more gross autoconf magic, figure out which struct field we need to

struct. If we find out we needed this partition after calculating size
requirements, then toss an error.

In packages, our description file contains:
key = value is here
type entries, and we passed "key " and " value is here" to our strtrim
function, causing us to always memmove the value portion to remove the
space. Since this is a throwaway buffer, do the advancing on our own before
trimming to save the need to shift memory around; "value is here" will now
be passed and strtrim will be responsible for trailing whitespace.

We did this in some but not all cases, assuming the 0 value coming out of
libarchive would not be a problem. However, this does not work for "fake"
filesystems such as rpc_pipefs, which reports a free block and total block
count of zero.
Fix this by not ever counting symlinks or directories, and adding a note
explaining that if we someday do count directories, their size needs to be
attributed to the proper place.
This patch also includes a few cleanups/performance tweaks- avoid calling
strlen() on the mountpoint directory string as much by storing this size in
our mountpoint struct, and push the snprintf() call up to the calculate
functions since we were already doing it here in the remove case.

This works for both local and sync databases in slightly different ways. For
the local database, we can use the directory hard link count on the local/
