The clang-format commits changed symlinks to copies of the files, so
there are duplicates of each file.
This reverts the following commits:

curve25519 comes from boringssl as well, move it to that directory.
See git log for which boringssl commit the implementation comes from,
and changes that were applied.
BRANCH=none
BUG=chromium:884905
TEST=make buildall -j, which also include basic tests.

- Move generic implementation to curve25519-generic.o
- Always use optimized version on cortex-m0.
- Rename .s files to .S, remove unnecessary lines in assembly files.
- Rename crypto_scalarmult_curve25519 to x25519_scalar_mult to match
the signature provided by the generic implementation.
- Replace some handcoded memcpy with function calls
- Remove unnecessary "volatile" specifications in the code.
BRANCH=none
BUG=b:62813194
TEST=To test old implementation only:
- Increase CONFIG_RO_SIZE to 60kb
- Increase console stack size to 2048

./util/flash_ec --board=hammer --image=build/hammer/x25519.bin
EC console: runtest, taskinfo
=> Used to takes ~4'17" to run (X25519 duration 256347 us).
1496/2048 stack size usage in CONSOLE task
=> Now takes ~1'25" to run (X25519 duration 84520 us)
732/2048 stack size usage in CONSOLE task
TEST=In test/x25519.c, uncomment #define TEST_X25519_1M_ITERATIONS
make BOARD=hammer PROJECT=x25519 TEST_BUILD=y
./util/flash_ec --board=hammer --image=build/hammer/x25519.bin
EC console: runtest, wait ~23 hours, test passes.
TEST=- Define CONFIG_CURVE25519_CORTEXM0 (next patch)

Keep only the most compact version of the curve25519 code
and remove the remaining unused code for easier compilation.
Do the minimal changes to make it compile in the EC code base,
there should be no real functional changes.
Re-use the wording from BoringSSL include/openssl/curve25519.h for the
header.

TEST=run x25519 on host (ie 'make run-x25519')
and the STM32L4 target:
make BOARD=eve_fp PROJECT=x25519 TEST_BUILD=y
./util/flash_ec --board=eve_fp --image=build/eve_fp/x25519.bin
execute 'runtest' in the console.

Import the implementation of the curve25519 public key cryptography
from BoringSSL.
It's the unmodified crypto/curve25519/curve25519.c file from the
repository at sha c034e2d3ce16df5f89134515bc113eb4f3a28e0e.
(current HEAD of chromium-stable branch)
It will be used as a primitive to implement a Diffie-Hellman exchange.
The test code in test/x25519.c is also imported unmodified
from BoringSSL crypto/curve25519/x25519_test.cc.
