Android might want to replace the system *sum (i.e. md5sum, sha256sum
etc) binaries with a symlink to the BoringSSL tool binary.
This change also allows the tool to figure out what to do based on
argv[0] if it matches one of the known commands.

This lets us run bssl speed at least. bssl client is currently compiled
out until we clean up our socket story on Windows and get it working.

This is cleaner than the OpenSSL code was, at least, but it's hardly
beautiful due to the "standard" that it's trying to implement. (See
[1].)
The references from the PKCS#8 code to various ciphers have digests have
been made into function pointer references rather than NIDs so that the
linker will be able to drop RC2 code for binaries that don't call PKCS#8
or #12 functions.
A bug that crashed OpenSSL/BoringSSL when parsing a malformed PKCS#8
structure has been fixed too.

Apart from the obvious little issues, this also works around a
(seeming) libtool/linker:
a.c defines a symbol:
int kFoo;
b.c uses it:
extern int kFoo;
int f() {
return kFoo;
}
compile them:
$ gcc -c a.c
$ gcc -c b.c
and create a dummy main in order to run it, main.c:
int f();
int main() {
return f();
}
this works as expected:
$ gcc main.c a.o b.o
but, if we make an archive:
$ ar q lib.a a.o b.o
and use that:
$ gcc main.c lib.a
Undefined symbols for architecture x86_64
"_kFoo", referenced from:
_f in lib.a(b.o)
(It doesn't matter what order the .o files are put into the .a)
Linux and Windows don't seem to have this problem.
nm on a.o shows that the symbol is of type "C", which is a "common symbol"[1].
Basically the linker will merge multiple common symbol definitions together.
If ones makes a.c read:
int kFoo = 0;
Then one gets a type "D" symbol - a "data section symbol" and everything works
just fine.
This might actually be a libtool bug instead of an ld bug: Looking at `xxd
lib.a | less`, the __.SYMDEF SORTED index at the beginning of the archive
doesn't contain an entry for kFoo unless initialised.

Initial fork from f2d678e6e89b6508147086610e985d4e8416e867 (1.0.2 beta).
(This change contains substantial changes from the original and
effectively starts a new history.)
