setdiscovery: stop limiting the number of local head we initially send
In our testing this limitation provides now real gain and instead triggers
pathological discovery timing for some repository with many heads.
See inline documentation for details.
Some timing below:
Mozilla try repository, (~1M revs, ~35K heads), discovery between 2 clones with
100 head missing on each side
before:
! wall 1.492111 comb 1.490000 user 1.450000 sys 0.040000 (best of 20)
! wall 1.813992 comb 1.820000 user 1.700000 sys 0.120000 (max of 20)

pypy (~100 heads, 317 heads) discovery between clones with only 42 common heads

Private repository (~1M revs, ~3K heads), discovery from a strip subset, about
100 changesets to be pulled.
