[bugfix] update align to flags in excess methods

gnzlbg 1773d5f953 [bugfix] update align to flags in excess methods 
- Also rename `align_to_flags(align, size)` to
  `layout_to_flags(layout)` because it was taking
  its parameters in a weird order (typically its
  size first and align second) and size + align
  is actually `Layout`.

Alex Crichton 984a60ef3e Clarify wording of license information in README. 
This text historically was copied verbatim from rust-lang/rust's own README [1]
with the intention of licensing projects the same as rustc's own license, namely
a dual MIT/Apache-2.0 license. The clause about "various BSD-like licenses"
isn't actually correct for almost all projects other than rust-lang/rust and
the wording around "both" was slightly ambiguous.

This commit updates the wording to match more precisely what's in the
standard library [2], namely clarifying that there aren't any BSD-like licenses
in this repository and that the source is licensable under either license, at
your own discretion.

[1]: f0fe716dbc (license)
[2]: f0fe716dbc/src/libstd/lib.rs (L5-L9)

Merge pull request #21 from SimonSapin/bind-all-the-functions 
Add bindings to all jemalloc public functions

Simon Sapin 87e5eff7e3 Re-export the jemalloc_sys crate as jemallocator::ffi 2017-10-30 16:19:46 +01:00
Simon Sapin e6ea8a94b4 Add bindings to all jemalloc public functions 
That is, those documented in http://jemalloc.net/jemalloc.3.html

For example `malloc` and `free` can be useful when implementing
callbacks for a C library that doesn’t provide a size when deallocating:

Simon Sapin dd5861f6de Swap the order of arguments to calloc. 
The documented order is (number of objects, size of each object),
though in practice they end up being multiplied together
and so are somewhat interchangeable.
