de49674fbd Use MALLOC_CONF rather than malloc_conf for tests.
malloc_conf does not reliably work with MSVC, which complains of
"inconsistent dll linkage", i.e. its inability to support the
application overriding malloc_conf when dynamically linking/loading.
Work around this limitation by adding test harness support for per test
shell script sourcing, and converting all tests to use MALLOC_CONF
instead of malloc_conf.

c4c2592c83 Update brace style.
Add braces around single-line blocks, and remove line breaks before
function-opening braces.

This resolves #537.

977103c897 Uniformly cast mallctl[bymib]() oldp/newp arguments to (void *).
This avoids warnings in some cases, and is otherwise generally good
hygiene.

487093d999 Fix regressions related extent splitting failures.
Fix a fundamental extent_split_wrapper() bug in an error path.

Fix extent_recycle() to deregister unsplittable extents before leaking
them.

Relax xallocx() test assertions so that unsplittable extents don't cause
test failures.

42faa9e3e0 Work around legitimate xallocx() failures during testing.
With the removal of subchunk size class infrastructure, there are no
large size classes that are guaranteed to be re-expandable in place
unless munmap() is disabled.  Work around these legitimate failures with
rallocx() fallback calls.  If there were no test configuration for which
the xallocx() calls succeeded, it would be important to override the
extent hooks for testing purposes, but by default these tests don't use
the rallocx() fallbacks on Linux, so test coverage is still sufficient.

fed1f9f367 Fix intermittent xallocx() test failures.
Modify xallocx() tests that expect to expand in place to use a separate
arena.  This avoids the potential for interposed internal allocations
from e.g. heap profile sampling to disrupt the tests.

This resolves #286.

044047fae1 Remove fragile xallocx() test case.
In addition to depending on map coalescing, the test depended on
munmap() being disabled so that chunk recycling would always succeed.

d260f442ce Fix xallocx(..., MALLOCX_ZERO) bugs.
Zero all trailing bytes of large allocations when
--enable-cache-oblivious configure option is enabled.  This regression
was introduced by 8a03cf039c (Implement
cache index randomization for large allocations.).

Zero trailing bytes of huge allocations when resizing from/to a size
class that is not a multiple of the chunk size.

allocations in place.

d82a5e6a34 Implement the *allocx() API.
Implement the *allocx() API, which is a successor to the *allocm() API.
The *allocx() functions are slightly simpler to use because they have
fewer parameters, they directly return the results of primary interest,
and mallocx()/rallocx() avoid the strict aliasing pitfall that
allocm()/rallocx() share with posix_memalign().  The following code
violates strict aliasing rules:

    foo_t *foo;
    allocm((void **)&foo, NULL, 42, 0);

whereas the following is safe:

    foo_t *foo;
    void *p;
    allocm(&p, NULL, 42, 0);
    foo = (foo_t *)p;

mallocx() does not have this problem:

    foo_t *foo = (foo_t *)mallocx(42, 0);
