fix various typos reported by spellintian

Most of them in (old) code comments. The two instances of user visible string changes the po files of the manpages are fixed up as well. Gbp-Dch: Ignore Reported-By: spellintian

Read dpkg tables to handle architecture wildcards

2017-01-17T00:43:50Z

Our implementation of wildcards was rudimentary. It worked for some common ones, but it was also broken: For example, armel matched any-armel, but should match any-arm. With this commit, we load the correct tables from dpkg. Supported are both triplets and quadruplet tables (the latter introduced in dpkg 1.18.11). There are some odd things we have to deal with in the cache filter for historical and API reasons: * The character "*" must be accepted as an alternative to any - in fact it may appear anywhere in the wildcard as we also allow fnmatch() style wildcard matching on the commandline. * The code might get passed an arch with a minus at the end, for example the cmdline "install apt:any-arm-" will first try to check if any-arm- is a valid architecture. We deal with this by rejecting any wildcard ending in a minus. * Triplets are actually implemented by extending them to faux quadruplets - by prepending a "base" component for the architecture tuple, and "any" if there is a wildcard component. Once we have constructed a wildcard, it is transformed into an fnmatch() expression for historical reasons. In the future, we should really get a tuple class and implement matching in a better, more explicit way. This does for now though - it passes all the test cases and accepts all things it should accept. Closes: #748936 Thanks: James Clarke for the initial patch

CMake: Add missing iconv dependency

2016-08-26T20:24:25Z

FreeBSD has two iconv systems: It ships an iconv.h itself, and symbols for that in the libc. But there's also the port of GNU libiconv, which unfortunately for us, Doxygen depends on. This changes things to prefer a separate libiconv library over the system one; that is, the port on FreeBSD. Gbp-Dch: ignore

Make root group configurable via ROOT_GROUP

2016-08-26T20:24:25Z

This is needed on BSD where root's default group is wheel, not root.

Make directory paths configurable

2016-08-26T20:17:54Z

This allows other vendors to use different paths, or to build your own APT in /opt for testing. Note that this uses + 1 in some places, as the paths we receive are absolute, but we need to strip of the initial /.

CMake: Handle Berkeley DB on FreeBSD

2016-08-26T13:49:14Z

The BSD systems still ship their own db.h with a historical BSD implementation, which is preferred by CMake, as it searches its default path first. We thus have to disable the DEFAULT_PATH for the search, unfortunately. We also need to pass the correct include directory to the target. Furthermore, on FreeBSD the library is called db-, so let's add db-5 to the list of allowed names. Gbp-Dch: ignore

CMake: Add FindLZ4 and FindLZMA

2016-08-26T13:49:14Z

This makes things work with /usr/local on FreeBSD. Gbp-Dch: ignore

CMake: Handle endian.h locations on other platforms

CMake: Discover docbook stylesheet in other locations

2016-08-23T15:52:41Z

Distributions seem to install this stuff all over the place, so let's add a common list of paths we know about.

CMake: Add Large File Support

2016-08-23T15:46:41Z

This module should cover all sorts of large file supports, as long as they either support the getconf LFS_CFLAGS command; or the _FILE_OFFSET_BITS=64 or _LARGE_FILES macros. Closes: #834767
