Corinna Vinschen 995d2a824a Cygwin: tape: Handle non-standard "no medium" error code 
Certain tape drives (known example: QUANTUM_ULTRIUM-HH6) return
the non-standard ERROR_NOT_READY rather than ERROR_NO_MEDIA_IN_DRIVE
if no media is present.  ERROR_NOT_READY is not documented as valid
return code from GetTapeStatus.  Without handling this error code
Cygwin's tape code can't report an offline state to user space.

Fix this by converting ERROR_NOT_READY to ERROR_NO_MEDIA_IN_DRIVE
where appropriate.

Add a debug_printf to mtinfo_drive::get_status to allow requesting
user info without having to rebuild the DLL.

Corinna Vinschen 732e0b395d Cygwin: Implement pthread_tryjoin_np and pthread_timedjoin_np 
- Move pthread_join to thread.cc to have all `join' calls in
  the same file (pthread_timedjoin_np needs pthread_convert_abstime
  which is static inline in thread.cc)
- Bump API version

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.
