/**
This function is used to manage the headers portion of an HTTP message by providing
the ability to add, remove, or replace HTTP headers.
@param[in] SeedMessageSize Size in bytes of the initial HTTP header. This can be zero.
@param[in] SeedMessage Initial raw unformatted HTTP header to be used as a base for
building a new unformatted HTTP header. If NULL, SeedMessageSize
is ignored. The buffer containing this message will be allocated
and released by the caller.
@param[in] DeleteCount Number of null-terminated HTTP header field names in DeleteList.
@param[in] DeleteList List of null-terminated HTTP header field names to remove from SeedMessage.
Only the field names are in this list because the field values are irrelevant
to this operation. If NULL, DeleteCount is ignored. The buffer containing the
list will be allocated and released by the caller.
@param[in] AppendCount Number of header fields in AppendList.
@param[in] AppendList List of HTTP headers to populate NewMessage with. If SeedMessage is not NULL,
AppendList will be appended to the existing list from SeedMessage in NewMessage.
@param[out] NewMessageSize Pointer to the size in bytes of the new unformatted HTTP header in NewMessage.
@param[out] NewMessage Pointer to a new unformatted HTTP header. The storage for this NewMessage is
allocated by the driver publishing this protocol, and must be freed by the caller.
@retval EFI_SUCCESS Add, remove, and replace operations succeeded.
@retval EFI_OUT_OF_RESOURCES Could not allocate memory for NewMessage.
