  Update URLs
  
  - Eliminate unnecessary "www."
  - Use HTTPS.
  - Update Java, MSYS, tdm-gcc, and NSIS URLs.
  - Update URL and title of Agner Fog's assembly language optimization
    manual.
  - Remove extraneous information about MASM and Borland Turbo Assembler
    and outdated NASM URLs from the x86 assembly headers, and mention
    Yasm.
