Modify userspace .org and RAMSTART expectations Instead of expecting a `USER_CODE` symbol to be set, we expect `.org` to be set in all userspace glue code. This gives us more flexibility with regards to how we manage that. Moreover, instead of making `USER_RAMSTART` mandatory, we make it default to the end of the binary, which is adequate in a majority of cases. Will be useful for my upcoming mega-commit... :)

.org 0x4800 ; in sync with USER_CODE in glue.asm
zasm: add support for "$" symbol Allows for the ".fill x-$" pattern.

zasm emul: bring back kernel/user distinction It was a bad idea to remove it. Now that I'm introducing the concept of a per-app glue file, it becomes much easier to build emulated zasm as a userspace app.

Rename blockdev's API routines to GetB/PutB The goal is to avoid mixing those routines with "character devices" (acia, vpd, kbd) which aren't block devices and have routines that have different expectations. This is a first step to fixing #64.
