Corinna Vinschen eb4bfe4621 cygwin: block devices: fix file offset after short writes 
When reading/writing block devices, Cygwin emulates Linux, providing
a byte-exact file position, albeit the underlying device drivers don't.

Unfortunately this only worked correctly for reading.  The raw_write
method failed to revalidate the buffer after the read-modify-write
cycle in case len is not a multiple of the sector length.  This in
turn resulted in lseek reporting a wrong file pointer.

Also, fix a condition for invalidating the buffer after writing from
a remaining read buffer.

Corinna Vinschen 33297d810d Cygwin: dlfcn: Fix reference counting 
The original dll_init code was living under the wrong assumption that
dll_dllcrt0_1 and in turn dll_list::alloc will be called for each
LoadLibrary call.  The same wrong assumption was made for
cygwin_detach_dll/dll_list::detach called via FreeLibrary.

In reality, dll_dllcrt0_1 gets only called once at first LoadLibrary
and cygwin_detach_dll once at last FreeLibrary.

In effect, reference counting for DLLs was completely broken after fork:

  parent:
    l1 = dlopen ("lib1");  // LoadLibrary, LoadCount = 1
    l2 = dlopen ("lib1");  // LoadLibrary, LoadCount = 2

    fork ();               // LoadLibrary in the child, LoadCount = 1!
      child:
        dlclose (l1);      // FreeLibrary actually frees the lib
        x = dlsym (l2);    // SEGV

* Move reference counting to dlopen/dlclose since only those functions
  have to keep track of loading/unloading DLLs in the application context.

* Remove broken accounting code from dll_list::alloc and dll_list::detach.

* Fix error handling in dlclose.
