Objecter: pg_interval_t::is_new_interval needs pgid from previous pool

When increasing the pg_num of a pool, an assert would fail since the
calculated pgid seed would be for the pool's new pg_num value instead
of the previous pg_num value.

hobject_t: decode future hobject_t::get_min() properly

The post-hammer wip-temp branch changed hobject_t::get_min() so that pool
is INT64_MIN instead of -1 and neglected to deal with the encoding compat
with older versions.  Compensate on hammer by mapping INT64_MIN to -1
locally.  See commit ff99af38df830e215359bfb8837bf310a2023a4d.

Note that this means upgrades from hammer to post-hammer *must* include
this fix prior to the upgrade.  This will need to be well-documented in the
release notes.

INT64_MIN one on decode.

Conditional-compile against minimal tcmalloc.

Certain older systems (SLE11 in this case) do not provide the full
tcmalloc functionality, due to e.g. incomplete libunwind
pieces. Use --with-tcmalloc-minimal to enable the cut-down
version.

Here's how the various mem allocator switches interact now:

--with-jemalloc: overrides --with-tcmalloc & --with-tcmalloc-minimal
--with-tcmalloc-minimal: overrides --with-tcmalloc
--with-tcmalloc: the default. use --without-tcmalloc to disable
