0a5489e37d Add --with-mangling.
Add the --with-mangling configure option, which can be used to specify
name mangling on a per public symbol basis that takes precedence over
--with-jemalloc-prefix.

Expose the memalign() and valloc() overrides even if
--with-jemalloc-prefix is specified.  This change does no real harm, and
simplifies the code.

b172610317 Simplify small size class infrastructure.
Program-generate small size class tables for all valid combinations of
LG_TINY_MIN, LG_QUANTUM, and PAGE_SHIFT.  Use the appropriate table to generate
all relevant data structures, and remove the distinction between
tiny/quantum/cacheline/subpage bins.

Remove --enable-dynamic-page-shift.  This option didn't prove useful in
practice, and it prevented optimizations.

Add Tilera architecture support.

ef8897b4b9 Make 8-byte tiny size class non-optional.
When tiny size class support was first added, it was intended to support
truly tiny size classes (even 2 bytes).  However, this wasn't very
useful in practice, so the minimum tiny size class has been limited to
sizeof(void *) for a long time now.  This is too small to be standards
compliant, but other commonly used malloc implementations do not even
bother using a 16-byte quantum  on systems with vector units (SSE2+,
AltiVEC, etc.).  As such, it is safe in practice to support an 8-byte
tiny size class on 64-bit systems that support 16-byte types.

0fee70d718 Do not enable lazy locking by default.
Do not enable lazy locking by default, because:
- It's fragile (applications can subvert detection of multi-threaded
  mode).
- Thread caching amortizes locking overhead in the default
  configuration.

4162627757 Remove the swap feature.
Remove the swap feature, which enabled per application swap files.  In
practice this feature has not proven itself useful to users.

746e77a06b Add the --with-private-namespace option.
Add the --with-private-namespace option to make it possible to work
around library-private symbols being exposed in static libraries.
