bookmarks: keep bookmarks in .hg/store if new config set
Bookmarks storage consists of two parts: (1) the set of bookmarks and
their positions, and (2) the current bookmark. The former can get
updated by exchange, while the latter cannot. However, they are both
stored in directly .hg/ and protected by repo.wlock(). As a result,
ugly workarounds were needed. This patch introduces a new config
option to store the set of bookmarks and their positions in .hg/store/
but still storing the current bookmark directory in .hg/. The config
option only takes effect at repo creation time. It results in a new
requirement being set.
