Remove DMA move operations

See merge request !41

Since we removed `move` from the dma API, bindings are now useless.

Poorly supported feature that doesn't play well with the rest of the
library and limits what we can do in the future.

[feature/ci] add bitmap methods, fasten tests

See merge request !42

[feature] add error codes and functions

See merge request !39

[fix] use local headers in aml.h

See merge request !40

To ensure that unit tests include the right version of the code, aml.h
should include local header. This also works for installed programs.

[refactor] use autoconf + m4 for version mngmt

See merge request !36

Use m4 to define autoconf-level version variables, following the naming
scheme of semver.org

To make use of these variables in the headers and sources, a
generated-header is added in aml/utils/version.h

Also add a simple test for that part of the lib.

Aml version

See merge request !35

Continue splitting headers.

See merge request !34

The overall strategy for now is to split the implementations into
distinct headers, but keep the generic APIs inside the main aml.h

[doc] add documentation on design/workflow

Closes #29

See merge request !33

Document design principles, coding guidelines, contribution workflow.

[refactor] make bitmasks closer to a real type

See merge request !32

While the current bitmask management is heavily inspired by libnuma, it is not
as easy to use has the libnuma API. This patch is an attempt to refactor
to code towards something cleaner.

Add No-op request capability to Scratch

Closes #18

See merge request !31

If an operation should not trigger any actual work, create a no-op
request to deal with it properly.

Related to #18.

Reorganisation of aml files

See merge request !30

- create one directory per building block in src and include
- keep one directory for tests, \
  otherwise automake make them "test suites"
- move to AC_OPENMP, which is from autoconf 2.62 (2008)

[ci] URL fix for gitlab CI.

See merge request !29

[fix] Embed custom jemalloc into libaml

Closes #26

See merge request !28

Force libtool to static link the PIC version of our jemalloc import into
libaml, making libaml standalone. This requires us to test some
additional libraries in our own configure (pthread, and dlopen).

This also solves the long-standing issue of `make check` only working after
`make install`, while removing our custom jemalloc from the installed
libraries.

Fixes #26.

Mbind is giving us trouble again, will need to spend time looking at it
carefully.

Modify the benchmarks to use the new functions.

Instead of asking the user to provide the offsets into a tiling, add a
function providing a tileid. This tileid corresponds to the in-memory
order of tiles, making the tilestart functions a lot simpler.

We still need to split the tileid for tilestart because scratchpads
create requests based on tileids.

Also add a unit test for tiling_2d, to make sure we're not doing
anything crazy.

Tiling 2d and its interfaces wasn't the right way of looking at 2d grids
of tiles. Rename the contig ones to provide the required features.

This patch provides aligned allocations for all areas. Simple tests
included.

Note that I haven't tested if it conflicts with arena-wide alignements.

We are going to need more of those flags, and keeping track of the
conversions is tricky. So let's use a copy of the macros.

mbind requires that the input ptr be aligned on a page.

NOTE: we could also figure out a way to ask jemalloc
for page-aligned allocations, but that would probably
be too much for each alloc.
