Rather than assume all dependencies are required for all programs, split them out. This will make packaging easier, as well as splitting the code to use subprojects. Note that due to the use of config.h semantics, in most cases the got_compat.h header file is now at the top of the .c file it is included in, so that it can handle the system header inclusion properly.

Accept flag parameter to optionally specify which pointers to free. This saves callers looping through the list to free pointers. ok + fix stsp@

Now that the handling of including sys/queue.h is better, there's no need to remove those lines from the source. Copy the location of those original sys/queue.h lines from upstream at the same line number, so as to avoid any conflicts in the future.

Throwing this into the mix for a while, we can always get rid of it again if it becomes annoying. No objections from stsp@

Move some bits from the libexec helper to the main process so we know if the patch was generated by git or not and finally document the automatic stripping of a/ and b/ prefixes added by git-diff(1). ok stsp@

This commit modifies the GoT main branch to be able to compile it under linux.

Such directory entries need special handling to make our directory traversal code work on filesystems that do not support the d_type optimization. I found this problem because references stored in the refs/ directory were not shown by 'got log' and 'tog log' when a repository is mounted over NFS. helpful feedback + ok millert@
