We use GNU statement expressions in crypto/md32_common.h, surrounded
by checks that GNU C is indeed used to compile. It seems that clang,
at least on Linux, pretends to be GNU C, therefore finds the statement
expressions and then warns about them.
The solution is to have clang be quiet about it.

./config would translate -d into having the target get a 'debug-'
prefix, and then run './Configure LIST' to find out if such a
debugging target exists or not.
With the recent changes, the separate 'debug-foo' targets are
disappearing, and we're giving the normal targets debugging
capabilities instead. Unfortunately, './config' wasn't changed to
match this new behavior.
This change introduces the arguments '--debug' and '--release' - the
latter just for orthogonality - to ./Configure, and ./config now
treats -d by adding '--debug' to the options for ./Configure.

Because base templates express inheritance of values, the attribute is
renamed to 'inherit_from', and texts about this talk about 'inheritance(s)'
rather than base templates.
As they were previously implemented, base templates that were listed
together would override one another, the first one acting as defaults for
the next and so on.
However, it was pointed out that a strength of inheritance would be to
base configurations on several templates - for example one for CPU, one
for operating system and one for compiler - and that requires a different
way of combining those templates. With this change, inherited values
from several inheritances are concatenated by default (keep on reading).
Also, in-string templates with the double-curly syntax are removed,
replaced with the possibility to have a configuration value be a coderef
(i.e. a 'sub { /* your code goes here */ }') that gets the list of values
from all inheritances as the list @_. The result of executing such a
coderef on a list of values is assumed to become a string. ANY OTHER
FORM OF VALUE WILL CURRENTLY BREAK.
As a matter of fact, an attribute in the current config with no value is
assumed to have this coderef as value:
sub { join(' ', @_) }
While we're at it, rename debug-[cl]flags to debug_[cl]flags and
nodebug-[cl]flags to release_[cl]flags.

Base templates are templates that are used to inherit from. They can
loosely be compared with parent class inheritance in object orientation.
They can be used for the same purpose as the variables with multi-field
strings are used in old-style string configurations.
Base templates are declared with the base_templates configuration
attribute, like so:
"example_target" => {
base_templates => [ "x86_asm", ... ]
...
}
Note: The value of base_templates MUST be an array reference (an array
enclosed in square brackets).
Any configuration target can be used as a base template by another. It
is also possible to have a target that's a pure template and not meant to
be used directly as a configuration target. Such a target is marked with
the template configuration attribute, like so:
"example_template" => {
template => 1,
cc => "mycc",
...
},
As part of this commit, all variables with multi-field strings have been
translated to pure templates. The variables currently remain since we
can't expect people to shift to hash table configurations immediately.

Template references are words with double brackets, and refer to the
same field in the target pointed at the the double bracketed word.
For example, if a target's configuration has the following entry:
'cflags' => '-DFOO {{x86_debug}}'
... then {{x86_debug}} will be replaced with the 'cflags' value from
target 'x86_debug'.
Note: template references are resolved recursively, and circular
references are not allowed

The reasoning is that configuration strings are hard to read and error
prone, and that a better way would be for them to be key => value hashes.
Configure is made to be able to handle target configuration values as a
string as well as a hash. It also does the best it can to combine a
"debug-foo" target with a "foo" target, given that they are similar
except for the cflags and lflags values. The latter are spliced into
options that are common for "debug-foo" and "foo", options that exist
only with "debug-foo" and options that exist only with "foo", and make
them into combinable attributes that holds common cflags, extra cflags
for debuggin and extra cflags for non-debugging configurations.
The next step is to make it possible to have template configurations.

Configure would load the glob "Configurations*". The problem with
this is that it also loads all kinds of backups of those
configurations that some editors do, like emacs' classic
'Configurations~'. The solution is to give them an extension, such as
'.conf', and make sure to end the glob with that.
Also, because 'Configurations.conf' makes for a silly name, and
because a possibly large number of configurations will become clutter,
move them to a subdirectory 'Configurations/', and rename them to
something more expressive, as well as something that sets up some form
of sorting order. Thus:
Configurations -> Configurations/10-main.conf
Configurations.team -> Configurations/90-team.conf
Finally, make sure that Configure sorts the list of files that 'glob'
produces, and adapt Makefile.org.

Move the build configuration table into separate files. The Configurations
file is standard configs, and Configurations.team is for openssl-team
members. Any other file, Configurations*, found in the same directory
as the Configure script, is loaded.
To add another file, use --config=FILE flags (which should probably be
an absolute path).

The previous defaulting to TERMIOS took away -DTERMIOS / -DTERMIO a
bit too enthusiastically. Windows/DOSish platforms of all sorts get
identified as OPENSSL_SYS_MSDOS, and they get a different treatment
altogether UNLESS -DTERMIO or -DTERMIOS is explicitely given with the
configuration. The answer is to restore those macro definitions for
the affected configuration targets.
Reviewed-by: Tim Hudson <tjh@openssl.org>
The rationale for this move is that TERMIOS is default, supported by
POSIX-1.2001, and most definitely on Linux. For a few other systems,
TERMIO may still be the termnial interface of preference, so we keep
-DTERMIO on those in Configure.
crypto/ui/ui_openssl.c is simplified in this regard, and will define
TERMIOS for all systems except a select few exceptions.
