17aac16946 use readdir to generate ea list
when given a null for FILE_GET_EA_INFORMATION, use READDIR to construct one with
 the full named attribute directory listing

new function read_entire_dir() allocates an initial buffer for readdir entries a
nd calls nfs41_readdir() repeatedly to fill it.  the buffer is realloc()ed as mo
re space is required, allowing the function to return a complete listing in a si
ngle buffer

new function calculate_ea_list_length() calculates the exact length of the FILE_
GET_EA_INFORMATION buffer required to hold all of the names from the directory l
isting

once the FILE_GET_EA_INFORMATION buffer is allocated, it is filled by populate_e
a_list() and cached with nfs41_open_state

handle_getexattr() remains largely unchanged

b2e6a60710 ea: refactor SetEaInfo for use on open
when open is given an ea buffer, pass it to new function nfs41_ea_set() after successful file creation.  matches NTFS behavior on all dispositions: sets EAs on FILE_CREATE, FILE_OVERWRITE, FILE_OVERWRITE_IF, FILE_SUPERSEDE.  does not set EAs on FILE_OPEN.  only sets EAs on FILE_OPEN_IF if file did not previously exist.  see new function create_with_ea()

nfs41_ea_set() returns nfs error codes.  uses NFS4ERR_FBIG when the EaValueLength exceeds NFS4_EASIZE (256).  this gets mapped to windows error ERROR_FILE_TOO_LARGE, which the driver now converts to STATUS_EA_TOO_LARGE
