use readdir to generate ea list

Browse source 
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
