Use a more descriptive user-agent string (similar to PV's before) in stagefright http requests.

#include <stdlib.h>

namespace android {

static const char *kUserAgent = "stagefright-http";

// Given a connected HTTPStream, determine if the given path redirects

// somewhere else, if so, disconnect the stream, update host path and port

// accordingly and return true, otherwise return false and leave the stream

        const KeyedVector<String8, String8> *overrides) {

    mHeaders = String8();

    mHeaders.append("User-Agent: ");

    mHeaders.append(kUserAgent);

    mHeaders.append("\r\n");

    mHeaders.append("User-Agent: stagefright/1.0 (Linux;Android ");

#if (PROPERTY_VALUE_MAX < 8)

#error "PROPERTY_VALUE_MAX must be at least 8"

#endif

    char value[PROPERTY_VALUE_MAX];

    property_get("ro.build.version.release", value, "Unknown");

    mHeaders.append(value);

    mHeaders.append(")\r\n");

    if (overrides == NULL) {

        return;
