crypto: add scalar mult functions returning ge_p3 instead of ge_p2
ge_scalarmult_p3
ge_double_scalarmult_precomp_vartime2_p3
ge_double_scalarmult_base_vartime_p3

This makes it possible to reuse the result without having to
convert back to unsigned char[32] and back to ge types.

7193b89fe5 Scrub keys from memory just before scope end.
Partially implements #74.

Securely erases keys from memory after they are no longer needed. Might have a
performance impact, which I haven't measured (perf measurements aren't
generally reliable on laptops).

Thanks to @stoffu for the suggestion to specialize the pod_to_hex/hex_to_pod
functions. Using overloads + SFINAE instead generalizes it so other types can
be marked as scrubbed without adding more boilerplate.

585c917691 Specify "524,288" iterations instead of "500,000"
CryptoNight does exactly 524,288 iterations over the scratchpad as defined in CNS008, saying 500,000 could be confusing. I know its meant to give a rough idea (around 500k) to the reader but if you are reading the code, might as well know the exact number.

wallet: fix output collision detection for view wallets
View wallets do not have the spend secret key, and are thus
unable to derive key images for incoming outputs. Moreover,
a previous patch set key images to zero as a means to mark
an output as having an unknown key image, so they could be
filled in when importing key images at a later time. That
later patch caused spurious collisions. We now use public
keys to detect duplicate outputs. Public keys obtained from
the blockchain are checked to be identical to the ones
derived locally, so can't be spoofed.

e1c7af35d4 cmake: transitive deps and remove deprecated LINK_*
Keep the immediate direct deps at the library that depends on them,
declare deps as PUBLIC so that targets that link against that library
get the library's deps as transitive deps.

Break dep cycle between blockchain_db <-> crytonote_core.
No code refactoring, just hide cycle from cmake so that
it doesn't complain (cycles are allowed only between
static libs, not shared libs).

This is in preparation for supproting BUILD_SHARED_LIBS cmake
built-in option for building internal libs as shared.

This was disabled earlier as part of diagnosing failing tests

adding -fno-strict-aliasing. So, re-enabling it back.

rct amount key modified as per luigi1111's recommendations
This allows the key to be not the same for two outputs sent to
the same address (eg, if you pay yourself, and also get change
back). Also remove the key amounts lists and return parameters
since we don't actually generate random ones, so we don't need
to save them as we can recalculate them when needed if we have
the correct keys.

The implementation of mul in asm breaks 'slow-hash' test when built with

fixed.
