crypto: Fix typo in documentation
Add 'frmptr' emulator type
fix valgrind error in erts/emulator/drivers/unix/ttsl_drv.c

Running some valgrind memory checking showed the error below:

==18040== Thread 6:
==18040== Source and destination overlap in memcpy(0xf3f3f04, 0xf3f3f08, 52)
==18040==    at 0x4C2CFA0: memcpy@@GLIBC_2.14 (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so)

This occurred on Linux using R15B01 while the shell was emitting a prompt,
but the same problem is still present in R16B.

Change the memcpy on line 845 of ttsl_drv.c to memmove as valgrind
suggests. After the change, verify with valgrind that the error no longer
occurs.

[megaco] Appup cleanup

Removed instruction for 3.16.0.2 since this version has
never existed in R16 and since we would otherwise have to
include a *lot* of module delete instructions.
Fix decode failure when AVP Length < 8

Such a length caused decode of a message with valid (24-bit) length to
fail. Note that the error detected is wrong: it should be 5014
(INVALID_AVP_LENGTH), not 3009 (INVALID_AVP_BITS). This will be dealt
with by OTP-11007.
Add correct footer to last run index page

[jinterface] Clean up hanging java nodes after each test case
[jinterface] Set max heap size for jvm when running echo_server

The test cases nc_SUITE:decompress_roundtrip and
nc_SUITE:compress_roundtrip fails on some machines with
OutOfMemoryException. This commit sets the max heap size for the jvm
to 256M in nc_SUITE in order to get around this.
