If a Binary field contains one or more spaces before a comma, the
code produced a segmentation fault, as it accidentally set a pointer
to 0 instead of the value of the pointer.
If the comma is at the beginning of the field, the code would
create a binStartNext that points one element before the start
of the string, which is undefined behavior.
We also need to check that we do not exit the string during the
replacement of spaces before commas: A string of the form " ,"
would normally exit the boundary of the Buffer:
binStartNext = offset 1 ','
binEnd = offset 0 ' '
isspace_ascii(*binEnd) = true => --binEnd
=> binEnd = - 1
We get rid of the problem by only allowing spaces to be eliminated
if they are not the first character of the buffer:
binStartNext = offset 1 ','
binEnd = offset 0 ' '
binEnd > buffer = false, isspace_ascii(*binEnd) = true
=> exit loop
=> binEnd remains 0

We support installing ./foo.deb (and ./foo.dsc for source) for a while
now, but it can be a bit clunky to work with those directly if you e.g.
build packages locally in a 'central' build-area.
The changes files also include hashsums and can be signed, so this can
also be considered an enhancement in terms of security as a user "just"
has to verify the signature on the changes file then rather than
checking all deb files individually in these manual installation
procedures.

The structure we parse the data into has a dedicated size field, but it
tends to be easier to handle it as a (very weak) checksum.
|
|
Now (55153bf94ff28a23318e79aa48242244c4d82b3c) that pkgTagFile can be
told to deal with all sorts of comments we can use this mode to parse
dsc (as by catch) and debian/control files properly even in the wake of
multiline fields spliced with comments like Build-Depends.

This converts all callers that read machine-generated data,
callers that might work with user input are not converted.

Doing this disables the implicit copy assignment operator (among others)
which would cause hovac if used on the classes as it would just copy the
pointer, not the data the d-pointer points to. For most of the classes
we don't need a copy assignment operator anyway and in many classes it
was broken before as many contain a pointer of some sort.
Only for our Cacheset Container interfaces we define an explicit copy
assignment operator which could later be implemented to copy the data
from one d-pointer to the other if we need it.

To have a chance to keep the ABI for a while we need all three to team
up. One of them missing and we might loose, so ensuring that they are
available is a very tedious but needed task once in a while.

Collect all hashes we can get from the source record and put them into a
HashStringList so that 'apt-get source' can use it instead of using
always the MD5sum.
We therefore also deprecate the MD5 struct member in favor of the list.
While at it, the parsing of the Files is enhanced so that records which
miss "Files" (aka MD5 checksums) are still searched for other checksums
as they include just as much data, just not with a nice and catchy name.
This is a cherry-pick of 1262d35 with some dirty tricks to preserve ABI.

For compatibility we use/provide and fill quiet some deprecated methods
and fields, which subsequently earns us a warning for using them. These
warnings therefore have to be disabled for these codeparts and that is
what this change does now in a slightly more elegant way.

The Buffer was allocated using strndup() so we need to free it using
free() instead of delete[]

Beside being a bit cleaner it hopefully also resolves oddball problems
I have with high levels of parallel jobs.

* Implement an ugly workaround for the 10000-character limit on the
Binaries field in debSrcRecordParser, until such time as some things
can be converted over to use STL data types (ABI change) (Closes: #236688)
* Increase default tagfile buffer from 32k to 128k; this arbitrary limit
should also be removed someday (Closes: #174945)
