gotadmin dump is used to export (part of) the history of the repository; at the moment it only generates git bundles (which are pack files with a header) but support to generate a fast-import stream is planned. ok/tweaks stsp and jamsek

Reorganize the reference validation and pathlist generation by removing the reflist and building a pathlist directly. The pathlist entries record the object id in their extra data pointer, which also allows several redundant reference lookups to be skipped. This will eventually simplify sending target reference names that do not match the local repo by adding another parameter to insert_sendable_ref for a remote reference. This remote name will be added to the pathlist, but validation and object id lookups will continue to be performed with the local reference. ok jamsek

Nothing appears to benefit from this being non-static, and it was missing from the public API headers as well. ok stsp@

Don't make -C imply -c (a break statement was missing). Detect -an and -cn conflicts. Simplify by removing unneeded check for conflicting -aC (since -C requires -c, we can rely on the -ac conflict being detected). Update the man page to say -cC is allowed.

now that got_get_repo_commits() doesn't look at `action' we can stop fetching the commits during the rendering and bubble up the call. This yields better error messages and better replies codes on failure.
