This improvement seems to roughly halve the time it takes to run the
ossl_lh_strcasehash function.

It should have no impact on the strings we hash and search for often (algorithm
names, property strings).

Reorganize local header files

Apart from public and internal header files, there is a third type called
local header files, which are located next to source files in the source
directory. Currently, they have different suffixes like

'*_lcl.h', '*_local.h', or '*_int.h'

This commit changes the different suffixes to '*_local.h' uniformly.

Reorganize private crypto header files

Currently, there are two different directories which contain internal
header files of libcrypto which are meant to be shared internally:

While header files in 'include/internal' are intended to be shared
between libcrypto and libssl, the files in 'crypto/include/internal'
are intended to be shared inside libcrypto only.

To make things complicated, the include search path is set up in such
a way that the directive #include "internal/file.h" could refer to
a file in either of these two directoroes. This makes it necessary
in some cases to add a '_int.h' suffix to some files to resolve this
ambiguity:

#include "internal/file.h" # located in 'include/internal'
#include "internal/file_int.h" # located in 'crypto/include/internal'

This commit moves the private crypto headers from

'crypto/include/internal' to 'include/crypto'

As a result, the include directives become unambiguous

#include "internal/file.h" # located in 'include/internal'
#include "crypto/file.h" # located in 'include/crypto'

hence the superfluous '_int.h' suffixes can be stripped.

The files 'store_int.h' and 'store.h' need to be treated specially;
they are joined into a single file.

Properties for implementation selection.

Properties are a sequence of comma separated name=value pairs. A name
without a corresponding value is assumed to be a Boolean and have the
true value 'yes'. Values are either strings or numbers. Strings can be
quoted either _"_ or _'_ or unquoted (with restrictions). There are no
escape characters inside strings. Number are either decimal digits or
'0x' followed by hexidecimal digits. Numbers are represented internally
as signed sixty four bit values.

Queries on properties are a sequence comma separated conditional tests.
These take the form of name=value (equality test), name!=value (inequality
test) or name (Boolean test for truth). Queries can be parsed, compared
against a definition or merged pairwise.

Don't make any changes to the lhash structure if we are going to fail

The lhash expand() function can fail if realloc fails. The previous
implementation made changes to the structure and then attempted to do a
realloc. If the realloc failed then it attempted to undo the changes it
had just made. Unfortunately changes to lh->p were not undone correctly,
ultimately causing subsequent expand() calls to increment num_nodes to a
value higher than num_alloc_nodes, which can cause out-of-bounds reads/
writes. This is not considered a security issue because an attacker cannot
cause realloc to fail.

This commit moves the realloc call to near the beginning of the function
before any other changes are made to the lhash structure. That way if a
failure occurs we can immediately fail without having to undo anything.

Thanks to Pavel Kopyl (Samsung) for reporting this issue.
