Bill Paul d329ad6035 Add preliminary support for PCMCIA devices in addition to PCI/cardbus.
if_ndis.c has been split into if_ndis_pci.c and if_ndis_pccard.c.
The ndiscvt(8) utility should be able to parse device info for PCMCIA
devices now. The ndis_alloc_amem() has moved from kern_ndis.c to
if_ndis_pccard.c so that kern_ndis.c no longer depends on pccard.

NOTE: this stuff is not guaranteed to work 100% correctly yet. So
far I have been able to load/init my PCMCIA Cisco Aironet 340 card,
but it crashes in the interrupt handler. The existing support for
PCI/cardbus devices should still work as before.

/*
* Sections in object code files can be sparse. That is, the
* section may occupy more space in memory that it does when
* stored in a disk file. In Windows PE files, each section header
* has a 'virtual size' and 'raw data size' field. The latter
* specifies the amount of section data actually stored in the
* disk file, and the former describes how much space the section
* should actually occupy in memory. If the vsize is larger than
* the rsize, we need to allocate some extra storage and fill
* it with zeros. (Think BSS.)
*
* The typical method of loading an executable file involves
* reading each segment into memory using the vaddr/vsize from
* each section header. We try to make a small optimization however
* and only pad/move segments when it's absolutely necessary, i.e.
* if the vsize is larger than the rsize. This conserves a little
* bit of memory, at the cost of having to fixup some of the values
* in the section headers.
