synchronous system calls

These synchronous might be useful, if you also target windows users:

filenames must be utf8 encoded (see comment to ECHARSET)
sometimes additional options are available, e.g. Fs.openfile

O_CLOEXEC and O_SHARE_DELETE, O_SHARE_WRITE, O_SHARE_READ don't exist, because these flags are unconditionally added by libuv, if the platform supports them.

val openfile : 
  ?perm:int ->
  mode:uv_open_flag list ->
  string ->
  Uwt_base.file Uwt_base.uv_result

parameter perm
defaults are 0o644

val read : 
  ?pos:int ->
  ?len:int ->
  Uwt_base.file ->
  buf:bytes ->
  int Uwt_base.uv_result

parameter pos
default is always zero

parameter len
default is always the length of the string / array / Bytes.t

val read_ba : 
  ?pos:int ->
  ?len:int ->
  Uwt_base.file ->
  buf:Uwt_base.buf ->
  int Uwt_base.uv_result

_ba function are unsafe. Bigarrays are passed directly to libuv (no copy to c heap or stack).

val write : 
  ?pos:int ->
  ?len:int ->
  Uwt_base.file ->
  buf:bytes ->
  int Uwt_base.uv_result

If the number of buffers is greater than IOV_MAX, newer libuv versions already contains code to circumvent this problem
