doc: introduce some minimalistic markdown without essential changes

The goal is to transform the standard documents

    README, INSTALL, SUPPORT, CONTRIBUTING, ...

from a pure text format into markdown format, but in such a way
that the documentation remains nicely formatted an easy readable
when viewed with an normal text editor.

To achieve this goal, we use a special form of 'minimalistic' markdown
which interferes as little as possible with the reading flow.

 * avoid [ATX headings][] and use [setext headings][] instead
   (works for `<h1>` and `<h2>` headings only).
 * avoid [inline links][] and use [reference links][] instead.
 * avoid [fenced code blocks][], use [indented-code-blocks][] instead.

The transformation will take place in several steps. This commit
introduces mostly changes the formatting and does not chang the
content significantly.

Refactor evp_pkey_make_provided() to do legacy to provider export

easier if we have a better separation between legacy support and

This changes moves the support of legacy key to provider side key
export from evp-keymgmt_util_export_to_provider() to
evp_pkey_make_provided(), and makes sure the latter is called from all

[BN] harden `BN_copy()` against leaks from memory accesses

`BN_copy()` (and indirectly `BN_dup()`) do not propagate the
`BN_FLG_CONSTTIME` flag: the propagation has been turned on and off a
few times in the past years, because in some conditions it has shown
unintended consequences in some code paths.

Without turning the propagation on once more, we can still improve
`BN_copy()` by avoiding to leak `src->top` in case `src` is flagged with
`BN_FLG_CONSTTIME`.
In this case we can instead use `src->dmax` as the number of words
allocated for `dst` and for the `memcpy` operation.

Barring compiler or runtime optimizations, if the caller provides `src`
flagged as const time and preallocated to a public size, no leak should
happen due to the copy operation.

[EC] harden EC_KEY against leaks from memory accesses

We should never leak the bit length of the secret scalar in the key,
so we always set the `BN_FLG_CONSTTIME` flag on the internal `BIGNUM`
holding the secret scalar.

This is important also because `BN_dup()` (and `BN_copy()`) do not
propagate the `BN_FLG_CONSTTIME` flag from the source `BIGNUM`, and
this brings an extra risk of inadvertently losing the flag, even when
the called specifically set it.

The propagation has been turned on and off a few times in the past
years because in some conditions has shown unintended consequences in
some code paths, so at the moment we can't fix this in the BN layer.

In `EC_KEY_set_private_key()` we can work around the propagation by
manually setting the flag after `BN_dup()` as we know for sure that
inside the EC module the `BN_FLG_CONSTTIME` is always treated
correctly and should not generate unintended consequences.

Setting the `BN_FLG_CONSTTIME` flag alone is never enough, we also have
to preallocate the `BIGNUM` internal buffer to a fixed public size big
enough that operations performed during the processing never trigger
a realloc which would leak the size of the scalar through memory
accesses.

Fixed Length
------------

The order of the large prime subgroup of the curve is our choice for
a fixed public size, as that is generally the upper bound for
generating a private key in EC cryptosystems and should fit all valid
secret scalars.

For preallocating the `BIGNUM` storage we look at the number of "words"
required for the internal representation of the order, and we
preallocate 2 extra "words" in case any of the subsequent processing
might temporarily overflow the order length.

Future work
-----------

A separate commit addresses further hardening of `BN_copy()` (and

[PROV][KEYMGMT][EC] Import/export of priv_key as padded const time BN

For EC keys it is particularly important to avoid leaking the bit length
of the secret scalar.

Key import/export should never leak the bit length of the secret
scalar in the key.

For this reason, on export we use padded BIGNUMs with fixed length,
using the new `ossl_param_bld_push_BN_pad()`.

When importing we also should make sure that, even if short lived,
the newly created BIGNUM is marked with the BN_FLG_CONSTTIME flag as
soon as possible, so that any processing of this BIGNUM might opt for
constant time implementations in the backend.

Setting the BN_FLG_CONSTTIME flag alone is never enough, we also have
to preallocate the BIGNUM internal buffer to a fixed size big enough
that operations performed during the processing never trigger a
realloc which would leak the size of the scalar through memory
accesses.

Fixed length

The order of the large prime subgroup of the curve is our choice for
a fixed public size, as that is generally the upper bound for
generating a private key in EC cryptosystems and should fit all valid
secret scalars.

For padding on export we just use the bit length of the order
converted to bytes (rounding up).

For preallocating the BIGNUM storage we look at the number of "words"
required for the internal representation of the order, and we
preallocate 2 extra "words" in case any of the subsequent processing
might temporarily overflow the order length.

Future work
-----------

To ensure the flag and fixed size preallocation persists upon
`EC_KEY_set_private_key()`, we need to further harden
`EC_KEY_set_private_key()` and `BN_copy()`.
This is done in separate commits.

TEST: Create test specific output directories

We had all tests run with test/test-runs/ as working directory, and
tests cleaned up after themselves...  which is well and good, until
you want to have a look at what went wrong when a complex test fails,
and you have to recreate everything it does manually.

To remedy this, we have OpenSSL::Test create the result directory
dynamically (and cleaning it up first if it's already there) and let
the test recipe have that as working directory.

Test recipes are now encouraged to name their diverse output files
uniquely, and not to clean them up, to allow a developer to have a
look at the files that were produced.

With continuous integration that allows this, the result directories
could also be archived and be left as a build artifact.

Make util/find-doc-nits runnable from the build tree

Because we generate an increasing number of POD files, some of them
