f2ab0eb644 Clean up linker script 
This patch does the following:

- Add .text.* to the .text section in the output
- Add an assertion that the trampoline does not overflow a page
- Add the .rodata section
- Make .sdata and .sdata.* (which is for small data) be absorbed into
  the .data section, because we don't need to distinguish between them;
  this prevents .sdata from appearing in the output
- Make the analogous change for .srodata and .sbss
- Make all the data sections 16-byte aligned

This patch also updates the .editorconfig for *.ld files.

8509784d80 Add implementations of memcmp and memcpy to ulib 
This is necessary because gcc may generate calls to memcmp, memset,
memcpy, and memmove when compiling with -nostdlib.

b150908354 add `-bios none' to silence qemu 
QEMU 4.1+ emits warnings if -bios is not given, as newer versions
will load the OpenSBI firmware in this case.  Pass `-bios none' to
avoid this issue.
