hack lshlib into happiness with mingw

_locking() for file locking; hardcode pagesize as 64k; use
lseek()/read()-write()/lseek() and buffers to emulate mmap().

I haven't actually tested all this lshlib functionality, but with this
change I can build an audioDB.dll which works well enough to be linked
into a binary which seems to work under Wine.

extern "C" {
#include "audioDB_API.h"
}
#include "audioDB-internals.h"

int audiodb_power(adb_t *adb) {
  if(!(adb->flags & O_RDWR)) {
    return 1;
  }
  if(adb->header->length > 0) {
    return 1;
  }

  adb->header->flags |= ADB_HEADER_FLAG_POWER;
  return audiodb_sync_header(adb);
}
