Josh Gao b00e66f754 Reland "adbd: don't close ep0 until we receive FUNCTIONFS_UNBIND." 
Read until we receive FUNCTIONFS_BIND after every USB descriptor setup,
instead of only after initial creation of the control fd, so we properly
handle a rebind caused by a change of the USB configuration.

This reverts commit 55b31933f41b1c550b788fa2054010c51f56111b.

Josh Gao 9dba0f5824 Revert "adbd: don't close ep0 until we receive FUNCTIONFS_UNBIND." 
We're only reading FUNCTIONFS_BIND on creation upon the first creation
of the control fd, which results in an abort when rebind happens (e.g.
when MTP is enabled) and we unexpectedly read FUNCTIONFS_BIND in the
second instantiation of the connection.

This reverts commit 2b668d3906.

repeatedly.

Josh Gao db64696b7c adbd: provide MS OS descriptors for WinUSB. 
Add Microsoft OS Descriptors so that on Windows, we get automatically
registered with the WinUSB driver instead of requiring a different INF
to be used with device with a different vendor ID.

Bug: http://b/68993980
Test: manually changed the vendor ID on a blueline and connected it to a Windows VM
