Add top-right "Share a link" and "Login" links to the menu bar, refs #10138

New js/topLinks.js drives two links at the top-right of the menu bar on all pages:

- Login: links to the login page when logged out; when logged in it shows the
username and opens an account dialog (My Sessions / My Custom Tracks /
My Track Hubs, change password, sign out).
- Share a link: on hgTracks, one click saves the current view as a session and
shows a copyable short link, with an optional "Specify name" rename step; works
logged-in or anonymously (reserved user "l"). On hgTrackUi and the hgc/hgGene
item-details popup it instead shares the page URL with the hgsid stripped and
the db argument kept.

hgSession gains two JSON endpoints (hgS_doSaveSessionJson, hgS_doRenameSessionJson)
that reuse saveCartAsSession() and addSessionLink(). The menu bar is patched in
lib/web.c (CGI pages) and hgMenubar.c (static pages) via comment placeholders in
globalNavBar.inc. On narrow/phone screens the links collapse into a menu icon with
a dropdown so they no longer overlap the menu.
