de40b43037 [winpr,stream] modify logging stream length checks
* Split length argument to nmemb and size for all Stream_CheckAndLogRequiredLength* functions
* Add new macros to allow setting nmemb and size arguments

74530a7931 [format strings] ensure __LINE__ is of type size_t
__LINE__ is not particularily well defined (most fall back to int).
We want to ensure that all the uses in a format string match the format
specifier, so do an explicit cast

2aefa9418d [winpr,stream] Added functions to read/write utf-8
* Stream_Write_UTF16_String_From_UTF8 writes a UTF-8 string to a
      stream in UTF-16 encoding
    * Stream_Read_UTF16_String_To_UTF8 reads a UTF-16 encoded string
      from the stream and returns it in UTF-8 encoding

983443749d Added Stream_EnsureValidity
This function  terminates a process if a stream was used incorrectly.
It will work similar to an assert, but it is not possible to compile
without this.

Purpose is to prevent problems with missing length/capacity checks

18a3fcf2fc Updated wStream API and added torough checks
* Do length/capacity checks in every read/write/seek function
  if WINPR_ASSERT is defined.
* Ensure s->pointer is valid, e.g. within s->buffer + s->capacity
  (Stream_Rewind, Stream_Seek, ...)
* Add return values to Stream_Set* functions so inalid arguments
  can be reported to the caller
* Deprecated problematic stream manipulation functions
  (Stream_SetBuffer, Stream_SetPointer, Stream_SetCapacity)
* Ensure length/capacity functions never return a value larger
  than the actual length/capacity

13e2a8834d winpr: add some functions to use wStream in a static way
It's sometime useful to create a stream aliasing a buffer on the stack, and
it's nice if we don't need some extra malloc for this.

Example use:
   BYTE buffer[20];
   wStream s;

   Stream_StaticInit(&s, buffer, sizeof(buffer));
   Stream_Write_UINT16(&s, 0xff01);
   Stream_Free(&s, FALSE);

f469e069dc stream: Stream_Ensure*Capacity: change return type
Change the return type of Stream_Ensure*Capacity from void to BOOL to be
able to detect realloc problems easily. Otherwise the only way to detect
this was to check if the capacity after the call was >= the required
size.
In case Stream_Ensure*Capacity fails the old memory is still available
and need to freed outside.

This commit also adds checks to most calls of Stream_Ensure*Capacity to
check if the call was successful.
