Remove unnecessary coroutine interactions

Only reading, saving, and deleting the config actually involve disk operations, and even the network operations have a 500ms timeout, so it doesn't make sense to have all of the methods support concurrency. The increased complexity outweighs the benefits of following the best practice of keeping disk and network operations off the main thread.

+ *
+ * As a general rule, curl_off_t shall not be mapped to off_t. This rule shall
+ * only be violated if off_t is the only 64-bit data type available and the

+ * The following macros and typedefs allow an ASN1_ITEM
+ * to be embedded in a structure and referenced. Since
+ * the ASN1_ITEM pointers need to be globally accessible
+ * (possibly from shared libraries) they may exist in
+ * different forms. On platforms that support it the
+ * ASN1_ITEM structure itself will be globally exported.
+ * Other platforms will export a function that returns
+ * an ASN1_ITEM pointer.
+ *
+ * To handle both cases transparently the macros below
+ * should be used instead of hard coding an ASN1_ITEM
+ * pointer in a structure.
+ *
+ * The structure will look like this:
+ *
+ * typedef struct SOMETHING_st {
+ *      ...
+ *      ASN1_ITEM_EXP *iptr;
+ *      ...
+ * } SOMETHING;
+ *
+ * It would be initialised as e.g.:
+ *
+ * SOMETHING somevar = {...,ASN1_ITEM_ref(X509),...};
+ *
+ * and the actual pointer extracted with:
+ *
+ * const ASN1_ITEM *it = ASN1_ITEM_ptr(somevar.iptr);
+ *
+ * Finally an ASN1_ITEM pointer can be extracted from an
+ * appropriate reference with: ASN1_ITEM_rptr(X509). This
+ * would be used when a function takes an ASN1_ITEM * argument.
