[PATCH v2 0/2] Allow building with the external sha1dc library

Hi,

this is the second attempt to allow linking with the external sha1dc shlib. Now I split to two patches: one for cleaning up of sha1dc plumbing codes, and another for adding the option to link with the external sha1dc lib.

Other changes from v1:
- Plumbing codes for external lib are also merged commonly in
  sha1dc_git.[ch]
- Check the conflict of extlib vs submodule
- Drop DC_SHA1_LINK, hoping that everyone is well-mannered
- Minor rephrasing / corrections of texts

thanks,

Takashi
