[PATCH 01/20] vl: Add missing "hw/boards.h" include

[Philippe Mathieu-Daudé]

vl.c calls machine_usb() declared in "hw/boards.h". Include it.

This fixes (when modifying unrelated headers):

  vl.c:1283:10: error: implicit declaration of function 'machine_usb' is 
invalid in C99 [-Werror,-Wimplicit-function-declaration]
      if (!machine_usb(current_machine)) {
           ^
  vl.c:1283:10: error: this function declaration is not a prototype 
[-Werror,-Wstrict-prototypes]
  vl.c:1283:22: error: use of undeclared identifier 'current_machine'
      if (!machine_usb(current_machine)) {
                       ^
